The header file is used by different userspace programs to inject packets
or to decode sniffed packets. It should therefore be available to them as
userspace header.
Also other components in the kernel (like the flow dissector) require
access to the packet definitions to be able to decode ETH_P_BATMAN ethernet
packets.

Historically, branches targeting the next release (and pulled in
linux-next) have been pushed on the l2-mtd repo and fixes branches on

Move all -next branches to linux-mtd.

Move the visorbus driver out of staging (drivers/staging/unisys/visorbus)
and to drivers/visorbus. Modify the configuration and makefiles so they
now reference the new location. The s-Par header file visorbus.h that is
referenced by all s-Par drivers, is being moved into include/linux.

The chip family of TILEPro and TILE-Gx was developed by Tilera, which
was eventually acquired by Mellanox. The tile architecture was added to
the kernel in 2010 and first appeared in 2.6.36.
Now at Mellanox we are developing new chips based on the ARM64
architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
our customers using tile architecture products are not, as far as we
know, looking to upgrade to newer kernel releases. In the absence of
someone in the community stepping up to take over maintainership, this
commit marks the architecture as orphaned.

A frequent source of build problems is poor handling of optional PM
support, almost all development is done with the PM options enabled
but they can be turned off. Currently few if any of the build test
services do this as standard as there is no standard config for it and
the use of selects and def_bool means that simply setting CONFIG_PM=n
doesn't do what is expected. To make this easier provide a fragement
that can be used with KCONFIG_ALLCONFIG to force PM off.
CONFIG_XEN is disabled as Xen uses hibernation callbacks which end up
turning on power management on architectures with Xen. Some cpuidle
implementations on ARM select PM so CONFIG_CPU_IDLE is disabled, and
some ARM architectures unconditionally enable PM so they are also
disabled.

To be able to run selftests without any hardware required we
need a software model. The model can also serve as an example
implementation for those implementing actual HW offloads.
The dummy driver have previously been extended to test SR-IOV,
but the general consensus seems to be against adding further
features to it.
Add a new driver for purposes of software modelling only.
eBPF and SR-IOV will be added here shortly, others are invited
to further extend the driver with their offload models.

including WMI work to provide an interface for SMBIOS tokens via sysfs
and WMI support for 2017+ Dell laptop models. SMM dispatcher code is

large change that introduces runtime PM support to the clk framework. Now we
properly call runtime PM operations on the device providing a clk when the clk
is in use. This helps on SoCs where the clks provided by a device need
something to be powered on before using the clks, like power domains or
regulators. It also helps power those things down when clks aren't in use. The
other core change is a devm API addition for clk providers so we can get rid of
a bunch of clk driver remove functions that are just doing
of_clk_del_provider().
Outside of the core, we have the usual addition of clk drivers and smattering
of non-critical fixes to existing drivers. The biggest diff is support for
Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch
of data.
By the way, we're trying something new here where we build the tree up with
topic branches. We plan to work this into our workflow so that we don't step
on each other's toes, and so the fixes branch can be merged on an as-needed
basis.
Core:
- Runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()
New Drivers:
- Mediatek MT2712 and MT7622
- Renesas R-Car V3M SoC
Updates:
- Runtime PM support for Samsung exynos5433/exynos4412 providers
- Removal of clkdev aliases on Samsung SoCs
- Convert clk-gpio to use gpio descriptors
- Various driver cleanups to match kernel coding style
- Amlogic Video Processing Unit VPU and VAPB clks
- Sigma-delta modulation for Allwinner audio PLLs
- Allwinner A83t Display clks
- Support for the second display unit clock on Renesas RZ/G1E
- Suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
- New clock ids for Rockchip rk3188 and rk3368 SoCs
- Various 'const' markings on clk_ops structures
- RPM clk support on Qualcomm MSM8996/MSM8660 SoCs

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"We have two changes to the core framework this time around.
The first being a large change that introduces runtime PM support to
the clk framework. Now we properly call runtime PM operations on the
device providing a clk when the clk is in use. This helps on SoCs
where the clks provided by a device need something to be powered on
before using the clks, like power domains or regulators. It also helps
power those things down when clks aren't in use.
The other core change is a devm API addition for clk providers so we
can get rid of a bunch of clk driver remove functions that are just
doing of_clk_del_provider().
Outside of the core, we have the usual addition of clk drivers and
smattering of non-critical fixes to existing drivers. The biggest diff
is support for Mediatek MT2712 and MT7622 SoCs, but those patches
really just add a bunch of data.
By the way, we're trying something new here where we build the tree up
with topic branches. We plan to work this into our workflow so that we
don't step on each other's toes, and so the fixes branch can be merged
on an as-needed basis.
Summary:
Core:
- runtime PM support for clk providers
- devm API for of_clk_add_hw_provider()
New Drivers:
- Mediatek MT2712 and MT7622
- Renesas R-Car V3M SoC
Updates:
- runtime PM support for Samsung exynos5433/exynos4412 providers
- removal of clkdev aliases on Samsung SoCs
- convert clk-gpio to use gpio descriptors
- various driver cleanups to match kernel coding style
- Amlogic Video Processing Unit VPU and VAPB clks
- sigma-delta modulation for Allwinner audio PLLs
- Allwinner A83t Display clks
- support for the second display unit clock on Renesas RZ/G1E
- suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
- new clock ids for Rockchip rk3188 and rk3368 SoCs
- various 'const' markings on clk_ops structures
- RPM clk support on Qualcomm MSM8996/MSM8660 SoCs"

"Nicolas Pitre's cramfs work"
* 'work.cramfs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
cramfs: rehabilitate it
cramfs: add mmap support
cramfs: implement uncompressed and arbitrary data block positioning
cramfs: direct memory access support
* Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable
'userspace flush' of persistent memory updates via filesystem-dax
mappings. It arranges for any filesystem metadata updates that may be
required to satisfy a write fault to also be flushed ("on disk") before
the kernel returns to userspace from the fault handler. Effectively
every write-fault that dirties metadata completes an fsync() before
returning from the fault handler. The new MAP_SHARED_VALIDATE mapping
type guarantees that the MAP_SYNC flag is validated as supported by the
filesystem's ->mmap() file operation.
* Add support for the standard ACPI 6.2 label access methods that
replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods. This
enables interoperability with environments that only implement the
standardized methods.
* Add support for the ACPI 6.2 NVDIMM media error injection methods.
* Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for latch
last shutdown status, firmware update, SMART error injection, and
SMART alarm threshold control.
* Cleanup physical address information disclosures to be root-only.
* Fix revalidation of the DIMM "locked label area" status to support
dynamic unlock of the label area.

"Add Jason Gunthorpe as co-maintainer of the RDMA stack.
The change is simply to add Jason Gunthorpe to the MAINTAINERS file
for the RDMA stack (and update him in the .mailmap). Jason and I have
talked offline, and Jason will be filing a ticket with the k.o
helpdesk to get an account on k.o, and then we will likely move the
rdma tree to an area where we can both access it and use a shared repo
+ individual topic branches + merged up for-next branch as the staging
basis for each release.
Timing here is nice because in the US we are headed into a holiday
period whereas Jason will be around to keep the patch flow progressing
(I guess Canadians do their equivalent to Thanksgiving in October, so
he doesn't have an excuse to ignore email for the next week ;-))"

- Rockchip rk3288 based Amarula Vyasa single-board computer
- Samsung Exynos5800 based Odroid HC1 single-board computer
For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic
and Allwinner platforms, but others were also active.
Rob Herring and many others worked on reducing the number of issues that
the latest version of 'dtc' now warns about. Unfortunately there is still
a lot left to do.
A rework of the ARM foundation model introduced several new files
for common variations of the model.

For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX,
Amlogic and Allwinner platforms, but others were also active.
Rob Herring and many others worked on reducing the number of issues
that the latest version of 'dtc' now warns about. Unfortunately there
is still a lot left to do.
A rework of the ARM foundation model introduced several new files for
common variations of the model"

Most of the commits are for defconfig changes, to enable newly added
drivers or features that people have started using. For the changed
lines lines, we have mostly cleanups, the affected platforms are
OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus
driver, with the intention of cleaning up more legacy code.
Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now
with a Quad-Core ARM Cortex-A7. According to the manufacturer,
it is intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
of chips meant for managed gigabit ethernet switches, based
around a Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2
and Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation.

kernel cycle:
Core:
- The pin control Kconfig entry PINCTRL is now turned into
a menuconfig option. This obviously has the implication of
making the subsystem menu visible in menuconfig. This is
happening because of two things:
- Intel have started to deploy and depend on pin controllers
in a way that is affecting users directly. This happens
on the highly integrated laptop chipsets named after
geographical places: baytrail, broxton, cannonlake,
cedarfork, cherryview, denverton, geminilake, lewisburg,
merrifield, sunrisepoint... It started a while back and
now it is ever more evident that this is crucial
infrastructure for x86 laptops and not an embedded
obscurity anymore. Users need to be aware.
- Pin control expanders on I2C and SPI that are
arch-agnostic. Currently Semtech SX150X and Microchip
MCP28x08 but more are expected. Users will have to be
able to configure these in directly for their set-up.
- Just go and select GPIOLIB now that we made sure that
GPIOLIB is a very vanilla subsystem. Do not depend on
it, if we need it, select it.
- Exposing the pin control subsystem in menuconfig uncovered
a bunch of obscure bugs that are now hopefully fixed,
all more or less pertaining to Blackfin.
- Unified namespace for cross-calls between pin control and
GPIO.
- New support for clock skew/delay generic DT bindings
and generic pin config options for this.
- Minor documentation improvements.
Various:
- The Renesas SH-PFC pin controller has evolved a lot. It seems
Renesas are churning out new SoCs by the minute.
- A bunch of non-critical fixes for the Rockchip driver.
- Improve the use of library functions instead of open coding.
- Support the MCP28018 variant in the MCP28x08 driver.
- Static constifying.

shortlog has the full details.
Note, there will be a merge conflict in drivers/misc/lkdtm_core.c when
merging to your tree as one lkdtm patch came in through the perf tree as
well as this one. The resolution is to take the const change that this
tree provides.
All of these have been in linux-next for quite a while with no reported

Pull rdma updates from Doug Ledford:
"This is a fairly plain pull request. Lots of driver updates across the
stack, a huge number of static analysis cleanups including a close to
50 patch series from Bart Van Assche, and a number of new features
inside the stack such as general CQ moderation support.
Nothing really stands out, but there might be a few conflicts as you
take things in. In particular, the cleanups touched some of the same
lines as the new timer_setup changes.
Everything in this pull request has been through 0day and at least two
days of linux-next (since Stephen doesn't necessarily flag new
errors/warnings until day2). A few more items (about 30 patches) from
Intel and Mellanox showed up on the list on Tuesday. I've excluded
those from this pull request, and I'm sure some of them qualify as
fixes suitable to send any time, but I still have to review them
fully. If they contain mostly fixes and little or no new development,
then I will probably send them through by the end of the week just to
get them out of the way.
There was a break in my acceptance of patches which coincides with the
computer problems I had, and then when I got things mostly back under
control I had a backlog of patches to process, which I did mostly last
Friday and Monday. So there is a larger number of patches processed in
that timeframe than I was striving for.

Pull arm64 updates from Will Deacon:
"The big highlight is support for the Scalable Vector Extension (SVE)
which required extensive ABI work to ensure we don't break existing
applications by blowing away their signal stack with the rather large
new vector context (<= 2 kbit per vector register). There's further
work to be done optimising things like exception return, but the ABI
is solid now.
Much of the line count comes from some new PMU drivers we have, but
they're pretty self-contained and I suspect we'll have more of them in
future.

This tag contains the core RISC-V Linux port, which has been through
nine rounds of review on various mailing lists. The port is not
complete: there's some cleanup patches moving through the review
process, a whole bunch of drivers that need some work, and a lot of
feature additions that will be needed.
The patches contained in this tag have been through nine rounds of
review on the various mailing lists. I have some outstanding cleanup
patches, but since there's been so much review on these patches I
thought it would be best to submit them as-is and then submit explicit
cleanup patches so everyone can review them. This first patch set is
big enough that it's a bit of a pain to constantly rewrite, and it's
caused a few headaches with various contributors.
The port is definately a work in progress. While what's there builds
and boots with 4.14, it's a bit hard to actually see anything happen
because there are no device drivers yet. I maintain a staging branch
that contains all the device drivers and cleanup that actually works,
but those patches won't all be ready for a while. I'd like to get what
we currently have into your tree so everyone can start working from a
single base -- of particular importance is allowing the glibc
upstreaming process to proceed so we can sort out any possibly lingering
user-visible ABI problems we might have.
Copied below is the ChangeLog that contains the history of this patch
set:
(v9) As per suggestions on our v8 patch set, I've split the core architecture code
out from our drivers and would like to submit this patch set to be included
into linux-next, with the goal being to be merged in during the next merge
window. This patch set is based on 4.14-rc2, but if it's better to have it
based on something else then I can change it around.
This patch set contains just the core arch code for RISC-V, so while it builds
an nominally boots, you can't print or take an interrupt so it's not that
useful. If you're looking to actually boot a system it would probably be
better to use the full patch set listed below.
We've collected a handful of tags from reviewers, and the remainder of the
patch set only got minimal feedback last time. Here's what changed:
* We now use the device tree to initialize the timer driver so it's less
tighly coupled with the arch port.
* I cleaned up the defconfigs -- there's actually now just one, and it's
empty. For now I think we're OK with what the kernel sets as defaults, but
I anticipate we'll begin to expand this as people start to use the port
more.
* The VDSO symbols version is sane.
* We WFI while spinning in the boot loop.
* A handful of comments have been added.
While there are still a handful of FIXMEs in this patch set, we've started to
get enough interest from various users and contributors that maintaining an out
of tree patch set is starting to become a big burden. Hopefully the patches
are good enough to merge now, which will at least get everyone working in a
more reasonable manner as we clean up the remaining issues.
This patch set is also availiable on github
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9-arch
as is the entire patch set necessary to get a more functional RISC-V system up
and running, including a handful of patches that aren't ready for upstream yet.
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9
Hopefully I've managed to get everyone's feedback
Here's the change highlights from the whole patch set:
(v8) I know it may not be the ideal time to submit a patch set right now, as
it's the middle of the merge window, but things have calmed down quite a bit in
the last month so I thought it would be good to get everyone on the same page.
There's been a handful of changes since the last patch set, but most of them
are fairly minor:
* We changed PAGE_OFFSET to allowing mapping more physical memory on 64-bit
systems. This is user configurable, as it triggers a different code model
that generates slightly less efficient code.
* The device tree binding documentation is back, I'd managed to lose it at some
point.
* We now pass the atomic64 test suite. The SBI timer driver has been
* refactored.
(v7) It's been a while since my last patch set, but the changes han been fairly
minimal:
* The PCI cleanup patches have been dropped, we'll do them as a separate patch
set later.
* We've the Kconfig entries from CONFIG_ISA_* to CONFIG_RISCV_ISA_*, to make
grep easier.
* There have been a handful of memory model related tweaks in I/O land,
particularly relating the PCI and the upcoming platform specification.
There are significant comments in the relevant files. This is still a WIP,
but I think we're close to getting as good as we're going to get until we
end up with some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are pretty
minimal:
* The patch set is now based on linux-next/master, which I believe is a better
base now that we're getting closer to upstream.
* EARLY_PRINTK is no longer an option. Since the SBI console is reasonable,
there's no penalty to enabling it (and thus no benefit to disabling it).
* The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly similar to the
v4 patch set. The most interesting changes include:
* We've moved back to a single patch set.
* SMP support has been fixed, I was accidentally running on a non-SMP
configuration. There were various mistakes all over the tree as a result of
this.
* The cmpxchg syscalls have been removed, as they were deemed a bad idea. As
a result, RISC-V Linux systems mandate the A extension. The corresponding
Kconfig entry to enable builds on non-A systems has been removed.
* A few more atomic fixes: mostly fence changes, but those resulted in a
handful of additional macros that were no longer necessary.
* riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
* The cmpxchg64 syscall is no longer enabled on 32-bit systems. It's not
possible to provide this on SMP systems, and it's not necessary as glibc
knows not to call it.
* We provide a ELF_HWCAP so users can determine the ISA of the machine the
kernel is running on.
* The multi-line comments are in a better form.
* There were a handful of headers that could be replaced with the asm-generic
versions, and a few unnecessary definitions.
* We no longer use printk, but instead use pr_*.
* A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
* We've split out all our drivers into separate patch sets, which I've already
sent out to the relevant maintainers. I haven't included those patches in
this patch set, but some of them are necessary to build our port. A git
tree that contains all our patch sets merged together lives at
<https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v3>.
* The patch set is now split up differently: rather than being split per
directory it is split per topic. Hopefully this will make it easier to
review the port on the mailing list. The split is a bit rough, so you
probably still want to look at the patch set as a whole.
* atomic.h has been completely rewritten and is hopefully now correct. I've
attempted to sanitize the various other memory model related code as well,
and I think it should all be sane now aside from a handful of FIXMEs
commented in the code.
* We've changed the cmpexchg syscall to always exist and to not be
multiplexed. There is also a VDSO entry for compare and exchange, which
allows kernels with the A extension to execute user code without the A
extension reasonably fast.
* Our user-visible register state now contains enough space for the Q
extension for 128-bit floating point, as well as a few words to allow
extensibility to future ISA extensions like the eventual V extension for
vectors.
* A handful of driver cleanups, but these have been split into separate patch
sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
* We've split out our drivers into the right places, which means now there's
a lot more patches. I'll be submitting these patches to various subsystem
maintainers and including them in any future RISC-V patch sets until
they've been merged.
* The SBI console driver has been completely rewritten to use the HVC helpers
and is now significantly smaller.
* We've begun to use weaker barriers as opposed to just the big "fence".
There's still some work to do here, specifically:
- We need fences in the relaxed MMIO functions.
- The non-relaxed MMIO functions are missing R/W bits on their fences.
- Many AMOs need the aq and rl bits set.
* We now have thread_info in task_struct. As a result, sscratch now contains
TP instead of SP. This was necessary because thread_info is no longer on
the stack.
* A few shared routines have been added that we use instead of creating
another arch copy.

Merge tag 'riscv-for-linus-4.15-arch-v9-premerge' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux
Pull RISC-V architecture support from Palmer Dabbelt:
"This contains the core RISC-V Linux port, which has been through nine
rounds of review on various mailing lists. The port is not complete:
there's some cleanup patches moving through the review process, a
whole bunch of drivers that need some work, and a lot of feature
additions that will be needed.
The patches contained in this tag have been through nine rounds of
review on the various mailing lists. I have some outstanding cleanup
patches, but since there's been so much review on these patches I
thought it would be best to submit them as-is and then submit explicit
cleanup patches so everyone can review them. This first patch set is
big enough that it's a bit of a pain to constantly rewrite, and it's
caused a few headaches with various contributors.
The port is definately a work in progress. While what's there builds
and boots with 4.14, it's a bit hard to actually see anything happen
because there are no device drivers yet. I maintain a staging branch
that contains all the device drivers and cleanup that actually works,
but those patches won't all be ready for a while. I'd like to get what
we currently have into your tree so everyone can start working from a
single base -- of particular importance is allowing the glibc
upstreaming process to proceed so we can sort out any possibly
lingering user-visible ABI problems we might have.
Copied below is the ChangeLog that contains the history of this patch
set:
(v9) As per suggestions on our v8 patch set, I've split the core
architecture code out from our drivers and would like to submit
this patch set to be included into linux-next, with the goal
being to be merged in during the next merge window. This patch
set is based on 4.14-rc2, but if it's better to have it based on
something else then I can change it around.
This patch set contains just the core arch code for RISC-V, so
while it builds an nominally boots, you can't print or take an
interrupt so it's not that useful. If you're looking to actually
boot a system it would probably be better to use the full patch
set listed below.
We've collected a handful of tags from reviewers, and the
remainder of the patch set only got minimal feedback last time.
Here's what changed:
- We now use the device tree to initialize the timer driver so
it's less tighly coupled with the arch port.
- I cleaned up the defconfigs -- there's actually now just one,
and it's empty. For now I think we're OK with what the kernel
sets as defaults, but I anticipate we'll begin to expand this
as people start to use the port more.
- The VDSO symbols version is sane.
- We WFI while spinning in the boot loop.
- A handful of comments have been added.
While there are still a handful of FIXMEs in this patch set,
we've started to get enough interest from various users and
contributors that maintaining an out of tree patch set is
starting to become a big burden. Hopefully the patches are good
enough to merge now, which will at least get everyone working in
a more reasonable manner as we clean up the remaining issues.
(v8) I know it may not be the ideal time to submit a patch set right
now, as it's the middle of the merge window, but things have
calmed down quite a bit in the last month so I thought it would
be good to get everyone on the same page. There's been a handful
of changes since the last patch set, but most of them are fairly
minor:
- We changed PAGE_OFFSET to allowing mapping more physical
memory on 64-bit systems. This is user configurable, as it
triggers a different code model that generates slightly less
efficient code.
- The device tree binding documentation is back, I'd managed to
lose it at some point.
- We now pass the atomic64 test suite
- The SBI timer driver has been refactored.
(v7) It's been a while since my last patch set, but the changes han
been fairly minimal:
- The PCI cleanup patches have been dropped, we'll do them as a
separate patch set later.
- We've the Kconfig entries from CONFIG_ISA_* to
CONFIG_RISCV_ISA_*, to make grep easier.
- There have been a handful of memory model related tweaks in
I/O land, particularly relating the PCI and the upcoming
platform specification. There are significant comments in the
relevant files. This is still a WIP, but I think we're close
to getting as good as we're going to get until we end up with
some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are
pretty minimal:
- The patch set is now based on linux-next/master, which I
believe is a better base now that we're getting closer to
upstream.
- EARLY_PRINTK is no longer an option. Since the SBI console is
reasonable, there's no penalty to enabling it (and thus no
benefit to disabling it).
- The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly
similar to the v4 patch set. The most interesting changes
include:
- We've moved back to a single patch set.
- SMP support has been fixed, I was accidentally running on a
non-SMP configuration. There were various mistakes all over
the tree as a result of this.
- The cmpxchg syscalls have been removed, as they were deemed a
bad idea. As a result, RISC-V Linux systems mandate the A
extension. The corresponding Kconfig entry to enable builds
on non-A systems has been removed.
- A few more atomic fixes: mostly fence changes, but those
resulted in a handful of additional macros that were no
longer necessary.
- riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
- The cmpxchg64 syscall is no longer enabled on 32-bit systems.
It's not possible to provide this on SMP systems, and it's
not necessary as glibc knows not to call it.
- We provide a ELF_HWCAP so users can determine the ISA of the
machine the kernel is running on.
- The multi-line comments are in a better form.
- There were a handful of headers that could be replaced with
the asm-generic versions, and a few unnecessary definitions.
- We no longer use printk, but instead use pr_*.
- A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
- We've split out all our drivers into separate patch sets,
which I've already sent out to the relevant maintainers. I
haven't included those patches in this patch set, but some of
them are necessary to build our port.
- The patch set is now split up differently: rather than being
split per directory it is split per topic. Hopefully this
will make it easier to review the port on the mailing list.
The split is a bit rough, so you probably still want to look
at the patch set as a whole.
- atomic.h has been completely rewritten and is hopefully now
correct. I've attempted to sanitize the various other memory
model related code as well, and I think it should all be sane
now aside from a handful of FIXMEs commented in the code.
- We've changed the cmpexchg syscall to always exist and to not
be multiplexed. There is also a VDSO entry for compare and
exchange, which allows kernels with the A extension to
execute user code without the A extension reasonably fast.
- Our user-visible register state now contains enough space for
the Q extension for 128-bit floating point, as well as a few
words to allow extensibility to future ISA extensions like
the eventual V extension for vectors.
- A handful of driver cleanups, but these have been split into
separate patch sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
- We've split out our drivers into the right places, which
means now there's a lot more patches. I'll be submitting
these patches to various subsystem maintainers and including
them in any future RISC-V patch sets until they've been
merged.

"fence". There's still some work to do here, specifically:

- Many AMOs need the aq and rl bits set.
- We now have thread_info in task_struct. As a result, sscratch
now contains TP instead of SP. This was necessary because
thread_info is no longer on the stack.
- A few shared routines have been added that we use instead of

There are no big surprising changes in this cycle, yet not too
boring, either. The biggest change from diffstat POV is the removal
of the legacy OSS driver codes that have been already disabled for a
long time. This will bring a few trivial merge conflicts.
As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support. Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.
Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the malicious
device accesses with a new helper code for endpoint sanity check.
- Lots of cleanups for ASoC Intel platform code, including support for
their open source audio firmware.
- Continued ASoC core componentization works.
- Support for scaling MCLK with sample rate in ASoC simple-card.
- Stabler PCM hot-unplug capability, especially for ASoC usages.

"This contains two bigger than usual tree-wide changes this time. They
all have proper acks, caused no merge conflicts in linux-next where
they have been for a while. They are namely:
- to-gpiod conversion of the i2c-gpio driver and its users (touching
arch/* and drivers/mfd/*)
- adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)
Other notable changes:
- i2c_boardinfo can now carry a dev_name to be used when the device
is created. This is because some devices in ACPI world need fixed
names to find the regulators.
- the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.
- at24 driver has way better OF support. And it has a new maintainer.
Thanks Bartosz for stepping up!

CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the

Nothing out of the ordinary in here, and no API changes or anything
like that. Just various new features for drivers, core changes, etc.
In particular, this pull request contains:
- A patch series from Bart, closing the whole on blk/scsi-mq queue
quescing.
- A series from Christoph, building towards hidden gendisks (for
multipath) and ability to move bio chains around.
- NVMe
- Support for native multipath for NVMe (Christoph).

of sync-all units. This goes all the way, as discussed previously
(me).
- Fix for missing wakeup on writeback timer adjustments (Yafang
Shao).
- Fix laptop mode on blk-mq (me).
- {mq,name} tupple lookup for IO schedulers, allowing us to have
alias names. This means you can use 'deadline' on both !mq and on
mq (where it's called mq-deadline). (me).
- blktrace race fix, oopsing on sg load (me).
- blk-mq optimizations (me).
- Obscure waitqueue race fix for kyber (Omar).
- NBD fixes (Josef).
- Disable writeback throttling by default on bfq, like we do on cfq
(Luca Miccio).

like any other request. This is a really nice cleanup.
- Series from Ming that improves merging on blk-mq with schedulers,
getting us closer to flipping the switch on scsi-mq again.
- BFQ updates (Paolo).
- blk-mq atomic flags memory ordering fixes (Peter Z).

Pull power management updates from Rafael Wysocki:
"There are no real big ticket items here this time.
The most noticeable change is probably the relocation of the OPP
(Operating Performance Points) framework to its own directory under
drivers/ as it has grown big enough for that. Also Viresh is now going
to maintain it and send pull requests for it to me, so you will see
this change in the git history going forward (but still not right
now).
Another noticeable set of changes is the modifications of the PM core,
the PCI subsystem and the ACPI PM domain to allow of more integration
between system-wide suspend/resume and runtime PM. For now it's just a
way to avoid resuming devices from runtime suspend unnecessarily
during system suspend (if the driver sets a flag to indicate its
readiness for that) and in the works is an analogous mechanism to
allow devices to stay suspended after system resume.
In addition to that, we have some changes related to supporting
frequency-invariant CPU utilization metrics in the scheduler and in
the schedutil cpufreq governor on ARM and changes to add support for
device performance states to the generic power domains (genpd)
framework.
The rest is mostly fixes and cleanups of various sorts.
Specifics:
- Relocate the OPP (Operating Performance Points) framework to its
own directory under drivers/ and add support for power domain
performance states to it (Viresh Kumar).
- Modify the PM core, the PCI bus type and the ACPI PM domain to
support power management driver flags allowing device drivers to

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

Small Things:
- Move OpenRISC docs into Documentation and clean them up
- Document previously undocumented devicetree bindings
- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as true"
get the architecture ready for SMP.
- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of the
necessary data-structures to be per-cpu.
- The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks
- sleep instead of spin on secondary wait
- support framepointers and STACKTRACE_SUPPORT
- enable LOCKDEP_SUPPORT and irqflags tracing
- timer sync: Add tick timer sync logic
- fix possible deadlock in timer sync, pointed out by mips guys
Note: the irqchip patch was reviewed with Marc and we agreed to push it
together with these patches.

- essential clean up for tpm_crb so that ARM64 and x86 versions do
not distract each other as much as before

Smack:

Capabilities:
- BPRM_FCAPS fixes, from Richard Guy Briggs:
The audit subsystem is adding a BPRM_FCAPS record when auditing
setuid application execution (SYSCALL execve). This is not expected
as it was supposed to be limited to when the file system actually
had capabilities in an extended attribute. It lists all
capabilities making the event really ugly to parse what is
happening. The PATH record correctly records the setuid bit and
owner. Suppress the BPRM_FCAPS record on set*id.

The biggest thing this release has been the conversion of the AC98 bus
to the driver model, that's been a long time coming so thanks to Robert
Jarzmik for his dedication there. Due to there being some AC97 MFD
there's a few fairly large changes in input and the MFD layer, mainly to
the wm97xx driver.
There's also some drivers/drm changes to support the new AMD Stoney
platform, these are shared with the DRM subsystem and should be being
merged via both.
Within the subsystem the overwhelming bulk of the changes is in the
Intel drivers which continue to need lots of cleanups and fixes, this
release they've also gained support for their open source firmware.
There's also some large changs in the core as Morimoto-san continues to
mirror operations into the component level in preparation for conversion
of drivers to that.
- The AC97 bus has finally caught up with the driver model thanks to
some dedicated and persistent work from Robert Jarzmik.
- Continued work from Morimoto-san on moving us towards being able to
use components for everything.
- Lots of cleanups for the Intel platform code, including support for
their open source audio firmware.
- Support for scaling MCLK with sample rate in simple-card.
- Support for AMD Stoney platform.

Currently we are leaking addresses from the kernel to user space. This
script is an attempt to find some of those leakages. Script parses
`dmesg` output and /proc and /sys files for hex strings that look like
kernel addresses.
Only works for 64 bit kernels, the reason being that kernel addresses on
64 bit kernels have 'ffff' as the leading bit pattern making greping
possible. On 32 kernels we don't have this luxury.
Scripts is _slightly_ smarter than a straight grep, we check for false
positives (all 0's or all 1's, and vsyscall start/finish addresses).
[ I think there is a lot of room for improvement here, but it's already
useful, so I'm merging it as-is. The whole "hash %p format" series is
expected to go into 4.15, but will not fix %x users, and will not
incentivize people to look at what they are leaking. - Linus ]

For WMI operations that are only Set or Query readable and writable sysfs
attributes created by WMI vendor drivers or the bus driver makes sense.
For other WMI operations that are run on Method, there needs to be a
way to guarantee to userspace that the results from the method call
belong to the data request to the method call. Sysfs attributes don't
work well in this scenario because two userspace processes may be
competing at reading/writing an attribute and step on each other's
data.
When a WMI vendor driver declares a callback method in the wmi_driver
the WMI bus driver will create a character device that maps to that
function. This callback method will be responsible for filtering
invalid requests and performing the actual call.
That character device will correspond to this path:
/dev/wmi/$driver
Performing read() on this character device will provide the size
of the buffer that the character device needs to perform calls.
This buffer size can be set by vendor drivers through a new symbol
or when MOF parsing is available by the MOF.
Performing ioctl() on this character device will be interpretd
by the WMI bus driver. It will perform sanity tests for size of
data, test them for a valid instance, copy the data from userspace
and pass iton to the vendor driver to further process and run.
This creates an implicit policy that each driver will only be allowed
a single character device. If a module matches multiple GUID's,
the wmi_devices will need to be all handled by the same wmi_driver.
The WMI vendor drivers will be responsible for managing inappropriate
access to this character device and proper locking on data used by
it.
When a WMI vendor driver is unloaded the WMI bus driver will clean
up the character device and any memory allocated for the call.

The dell-smbios stack only currently uses an SMI interface which grants
direct access to physical memory to the firmware SMM methods via a pointer.
This dispatcher driver adds a WMI-ACPI interface that is detected by WMI
probe and preferred over the SMI interface in dell-smbios.
Changing this to operate over WMI-ACPI will use an ACPI OperationRegion
for a buffer of data storage when SMM calls are performed.
This is a safer approach to use in kernel drivers as the SMM will
only have access to that OperationRegion.

This splits up the dell-smbios driver into two drivers:
* dell-smbios
* dell-smbios-smm
dell-smbios can operate with multiple different dispatcher drivers to
perform SMBIOS operations.
Also modify the interface that dell-laptop and dell-wmi use align to this
model more closely. Rather than a single global buffer being allocated
for all drivers, each driver will allocate and be responsible for it's own
buffer. The pointer will be passed to the calling function and each
dispatcher driver will then internally copy it to the proper location to
perform it's call.
Add defines for calls used by these methods in the dell-smbios.h header
for tracking purposes.

Currently userspace tools can access system tokens via the dcdbas
kernel module and a SMI call that will cause the platform to execute
SMM code.
With a goal in mind of deprecating the dcdbas kernel module a different
method for accessing these tokens from userspace needs to be created.
This is intentionally marked to only be readable as a process with
CAP_SYS_ADMIN as it can contain sensitive information about the
platform's configuration.
While adding this interface I found that some tokens are duplicated.
These need to be ignored from sysfs to avoid duplicate files.

MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

IPI driver for the Open Multi-Processor Interrupt Controller (ompic) as
described in the Multi-core support section of the OpenRISC 1.2
architecture specification:
https://github.com/openrisc/doc/raw/master/openrisc-arch-1.2-rev0.pdf
Each OpenRISC core contains a full interrupt controller which is used in
the SMP architecture for interrupt balancing. This IPI device, the
ompic, is the only external device required for enabling SMP on
OpenRISC.
Pending ops are stored in a memory bit mask which can allow multiple
pending operations to be set and serviced at a time. This is mostly
borrowed from the alpha IPI implementation.

Removed both imgtec email addresses and added back mine for
occasional reviews, also changed from Maintained to Odd Fixes to

MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:
- Have 10 or more patches in mainline authored using an @imgtec.com
email address, or any patches dated within the past year.
- Are still with Imagination but leaving as part of the MIPS business
unit, as determined from an internal email address list.
- Haven't already updated their email address (ie. JamesH) or expressed
a desire to be excluded (ie. Maciej).
- Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
myself.
New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list. An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.
Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

Perhaps long overdue, add a documentation file for filesystem-level
encryption, a.k.a. fscrypt or fs/crypto/, to the Documentation
directory. The new file is based loosely on the latest version of the
"EXT4 Encryption Design Document (public version)" Google Doc, but with
many improvements made, including:
- Reflect the reality that it is not specific to ext4 anymore.
- More thoroughly document the design and user-visible API/behavior.
- Replace outdated information, such as the outdated explanation of how
encrypted filenames are hashed for indexed directories and how
encrypted filenames are presented to userspace without the key.
(This was changed just before release.)
For now the focus is on the design and user-visible API/behavior, not on
how to add encryption support to a filesystem --- since the internal API
is still pretty messy and any standalone documentation for it would
become outdated as things get refactored over time.

Since no complaints have been raised after disabling the build of OSS
(Open Sound System) by the commit 31cbee6a56 ("sound: Disable the
build of OSS drivers"), let's finally drop the whole code and
documentation.
Some glue codes are still left intact since sound/oss/dmasound stuff
remains -- which is an independent implementation solely for m68k, and
it's not covered by ALSA yet.
Also, a couple of API header files (linux/sound.h and
linux/soundcard.h) are kept remaining as well, since the OSS API
itself is still supported by ALSA OSS emulation, and applications can
refer to these.
Where we're at it, some help texts in the top-level Kconfig are
adjusted, too (who still needs to specify I/O port in kbuild
nowadays?).

Several conflicts here.
NFP driver bug fix adding nfp_netdev_is_nfp_repr() check to
nfp_fl_output() needed some adjustments because the code block is in
an else block now.
Parallel additions to net/pkt_cls.h and net/sch_generic.h
A bug fix in __tcp_retransmit_skb() conflicted with some of
the rbtree changes in net-next.
The tc action RCU callback fixes in 'net' had some overlap with some
of the recent tcf_block reworking.
