The meaning of sym->kernel is obscure; it is set for in-kernel symbols
loaded from Modules.symvers. This happens only when we are building
external modules, and it is used to determine whether to dump symbols
to $(KBUILD_EXTMOD)/Modules.symvers
It is clearer to remember whether the symbol or module came from a dump
file or ELF object.
This changes the KBUILD_EXTRA_SYMBOLS behavior. Previously, symbols
loaded from KBUILD_EXTRA_SYMBOLS are accumulated into the current
$(KBUILD_EXTMOD)/Modules.symvers
Going forward, they will be only used to check symbol references, but
not dumped into the current $(KBUILD_EXTMOD)/Modules.symvers. I believe
this makes more sense.
sym->vmlinux will have no user. Remove it too.

Some vendors like HPe or Dell, encode the release version of their BIOS
in the "System BIOS {Major|Minor} Release" fields of Type 0.
This information is used to know which bios release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 65.27 bios is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/bios_release
65.27
[root@t1700 ~]#
Servers that have a BMC encode the release version of their firmware in the
"Embedded Controller Firmware {Major|Minor} Release" fields of Type 0.
This information is used to know which BMC release actually runs.
It could be used for some quirks, debugging sessions or inventory tasks.
A typical output for a Dell system running the 3.75 bmc release is :
[root@t1700 ~]# cat /sys/devices/virtual/dmi/id/ec_firmware_release

Merge tag 'afs-next-20200604' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull AFS updates from David Howells:
"There's some core VFS changes which affect a couple of filesystems:
- Make the inode hash table RCU safe and providing some RCU-safe
accessor functions. The search can then be done without taking the
inode_hash_lock. Care must be taken because the object may be being
deleted and no wait is made.
- Allow iunique() to avoid taking the inode_hash_lock.
- Allow AFS's callback processing to avoid taking the inode_hash_lock
when using the inode table to find an inode to notify.
- Improve Ext4's time updating. Konstantin Khlebnikov said "For now,
I've plugged this issue with try-lock in ext4 lazy time update.
This solution is much better."
Then there's a set of changes to make a number of improvements to the
AFS driver:
- Improve callback (ie. third party change notification) processing
by:
(a) Relying more on the fact we're doing this under RCU and by
using fewer locks. This makes use of the RCU-based inode
searching outlined above.
(b) Moving to keeping volumes in a tree indexed by volume ID
rather than a flat list.
(c) Making the server and volume records logically part of the
cell. This means that a server record now points directly at
the cell and the tree of volumes is there. This removes an N:M
mapping table, simplifying things.
- Improve keeping NAT or firewall channels open for the server
callbacks to reach the client by actively polling the fileserver on
a timed basis, instead of only doing it when we have an operation
to process.
- Improving detection of delayed or lost callbacks by including the
parent directory in the list of file IDs to be queried when doing a
bulk status fetch from lookup. We can then check to see if our copy
of the directory has changed under us without us getting notified.
- Determine aliasing of cells (such as a cell that is pointed to be a
DNS alias). This allows us to avoid having ambiguity due to
apparently different cells using the same volume and file servers.
- Improve the fileserver rotation to do more probing when it detects
that all of the addresses to a server are listed as non-responsive.
It's possible that an address that previously stopped responding
has become responsive again.
Beyond that, lay some foundations for making some calls asynchronous:
- Turn the fileserver cursor struct into a general operation struct
and hang the parameters off of that rather than keeping them in
local variables and hang results off of that rather than the call
struct.
- Implement some general operation handling code and simplify the
callers of operations that affect a volume or a volume component
(such as a file). Most of the operation is now done by core code.
- Operations are supplied with a table of operations to issue
different variants of RPCs and to manage the completion, where all
the required data is held in the operation object, thereby allowing
these to be called from a workqueue.
- Put the standard "if (begin), while(select), call op, end" sequence
into a canned function that just emulates the current behaviour for
now.
There are also some fixes interspersed:
- Don't let the EACCES from ICMP6 mapping reach the user as such,
since it's confusing as to whether it's a filesystem error. Convert
it to EHOSTUNREACH.
- Don't use the epoch value acquired through probing a server. If we
have two servers with the same UUID but in different cells, it's
hard to draw conclusions from them having different epoch values.
- Don't interpret the argument to the CB.ProbeUuid RPC as a
fileserver UUID and look up a fileserver from it.
- Deal with servers in different cells having the same UUIDs. In the
event that a CB.InitCallBackState3 RPC is received, we have to
break the callback promises for every server record matching that
UUID.
- Don't let afs_statfs return values that go below 0.
- Don't use running fileserver probe state to make server selection
and address selection decisions on. Only make decisions on final
state as the running state is cleared at the start of probing"

A few large, long discussed works this time. The RNBD block driver has
been posted for nearly two years now, and the removal of FMR has been a
recurring discussion theme for a long time. The usual smattering of
features and bug fixes.
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and a
mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block RDMA
device specific to ionos's cloud environment. It brings strong multipath
and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs and
drivers. FRWR should be preferred for at least a decade now.

Core changes:
- A new GPIO aggregator driver has been merged: this can
join a few select GPIO lines into a new aggregated GPIO
chip. This can be used for security: a process can be
granted access to only these lines, for example for
industrial control. Another way to use this is to
reexpose certain select lines to a virtual machine or
container.
- Warn if the gpio-line-names is too long in he DT parser
core.
- GPIO lines can now be looked up by line name in addition
to being looked up by offset.
New drivers:
- A new generic regmap GPIO driver has been merged. Too
many regmap drivers are starting to look like each other
so we need to create some common ground and try to move
drivers over to using that.
- The F7188X driver now supports F81865.
Driver improvements:
- Large improvements to the PCA953x expander, get multiple lines
and several cleanups.
- Large improvements to the DesignWare DWAPB driver, and Sergey
Semin has volunteered to maintain it.
- PL061 can now be built as a module, this is part of a bigger
effort to make the ARM platforms more modular.

When there are many DM multipath devices it really helps to have

part of.

Add more DMDEBUG that shows arguments passed and caller, and another
that shows state of related flags at end of queue_if_no_path().
Also add queue_if_no_path DMDEBUG to multipath_resume().
Signed-off-by: Mike Snitzer <snitzer@redhat.com>
Do not allow saving disabled queue_if_no_path if already saved as
enabled; implies multiple suspends (which shouldn't ever happen). Log
if this unlikely scenario is ever triggered.
Also, only write MPATHF_SAVED_QUEUE_IF_NO_PATH during presuspend or if
"fail_if_no_path" message. MPATHF_SAVED_QUEUE_IF_NO_PATH is no longer
always modified, e.g.: even if queue_if_no_path()'s save_old_value
argument wasn't set. This just implies a bit tighter control over
the management of MPATHF_SAVED_QUEUE_IF_NO_PATH. Side-effect is
multipath_resume() doesn't reset MPATHF_QUEUE_IF_NO_PATH unless
MPATHF_SAVED_QUEUE_IF_NO_PATH was set (during presuspend); and at that
time the MPATHF_SAVED_QUEUE_IF_NO_PATH bit gets cleared. So
MPATHF_SAVED_QUEUE_IF_NO_PATH's use is much more narrow in scope.
Last, but not least, do _not_ disable queue_if_no_path during noflush
suspend. There is no need/benefit to saving off queue_if_no_path via
MPATHF_SAVED_QUEUE_IF_NO_PATH and clearing MPATHF_QUEUE_IF_NO_PATH for
noflush suspend -- by avoiding this needless queue_if_no_path flag
churn there is less potential for MPATHF_QUEUE_IF_NO_PATH to get lost.
Which avoids potential for IOs to be errored back up to userspace
during DM multipath's handling of path failures.
That said, this last change papers over a reported issue concerning
request-based dm-multipath's interaction with blk-mq, relative to
suspend and resume: multipath_endio is being called _before_
multipath_resume. This should never happen if DM suspend's
blk_mq_quiesce_queue() + dm_wait_for_completion() is genuinely waiting
for all inflight blk-mq requests to complete. Similarly:
drivers/md/dm.c:__dm_resume() clearly calls dm_table_resume_targets()
_before_ dm_start_queue()'s blk_mq_unquiesce_queue() is called. If
the queue isn't even restarted until after multipath_resume(); the BIG
question that still needs answering is: how can multipath_end_io beat
multipath_resume in a race!?

Remove micro-optimization that infers device is between presuspend and
resume (was done purely to avoid call to dm_noflush_suspending, which
isn't expensive anyway).

Checking the tertiary superblock just consists of validating UUIDs,

To support multiple template digests, the static array entry->digest has
been replaced with a dynamically allocated array in commit aa724fe18a
("ima: Switch to dynamically allocated buffer for template digests"). The
array is allocated in ima_alloc_init_template() and if the returned pointer
is NULL, ima_free_template_entry() is called.
However, (*entry)->template_desc is not yet initialized while it is used by
ima_free_template_entry(). This patch fixes the issue by directly freeing
*entry without calling ima_free_template_entry().

These are updates to SoC specific drivers that did not have
another subsystem maintainer tree to go through for some
reason:
- Some bus and memory drivers for the MIPS P5600 based
Baikal-T1 SoC that is getting added through the MIPS tree.
- There are new soc_device identification drivers for TI K3,
Qualcomm MSM8939
- New reset controller drivers for NXP i.MX8MP, Renesas
RZ/G1H, and Hisilicon hi6220
- The SCMI firmware interface can now work across ARM SMC/HVC
as a transport.
- Mediatek platforms now use a new driver for their "MMSYS"
hardware block that controls clocks and some other aspects
in behalf of the media and gpu drivers.
- Some Tegra processors have improved power management
support, including getting woken up by the PMIC and cluster
power down during idle.
- A new v4l staging driver for Tegra is added.
- Cleanups and minor bugfixes for TI, NXP, Hisilicon,
Mediatek, and Tegra.

One new platform gets added, the Realtek RTD1195, which is an older
Cortex-a7 based relative of the RTD12xx chips that are already supported
in arch/arm64. The platform may also be extended to support running
32-bit kernels on those 64-bit chips for memory-constrained machines.
In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742,
an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally
released in 2016 as one of the last high-end 32-bit designs.
There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics
from old board code into device tree files.
The Versatile Express platform is made more modular, with built-in
drivers now becoming loadable modules. This is part of a greater effort
for the Android OS to have a common kernel binary for all platforms and
any platform specific code in loadable modules.
The PXA platform drops support for Compulab's pxa2xx boards that had
rather unusual flash and PCI drivers but no known users remaining.
All device drivers specific to those boards can now get removed as
well.
Across platforms, there is ongoing cleanup, with Geert and Rob
revisiting some a lot of Kconfig options.
