7de3f1423f KVM: s390: Add new reset vcpu API 
The architecture states that we need to reset local IRQs for all CPU
resets. Because the old reset interface did not support the normal CPU
reset we never did that on a normal reset.

Let's implement an interface for the missing normal and clear resets
and reset all local IRQs, registers and control structures as stated
in the architecture.

Userspace might already reset the registers via the vcpu run struct,
but as we need the interface for the interrupt clearing part anyway,
we implement the resets fully and don't rely on userspace to reset the
rest.

Pull FIELD_SIZEOF conversion from Kees Cook:
 "A mostly mechanical treewide conversion from FIELD_SIZEOF() to
  sizeof_field(). This avoids the redundancy of having 2 macros
  (actually 3) doing the same thing, and consolidates on sizeof_field().
  While "field" is not an accurate name, it is the common name used in
  the kernel, and doesn't result in any unintended innuendo.

  As there are still users of FIELD_SIZEOF() in -next, I will clean up
  those during this coming development cycle and send the final old
  macro removal patch at that time"

7347f09a19 First set of fixes for IIO in the 5.5 cycle. 
Mixture of old things people have just hit, and a few late breaking
 issues with things that went in during the merge window.
 
 Being sent promptly to resolve potential DT breakage causing
 issues for binding test builds.

   - Avoid reading extra data from the device over what was intended.
 * ad7124
   - Enable the internal reference when in use.
 * ad7292
   - Fix up license for newly added binding.  Better to not have this go
     out in a release with more limited header than intended.
   - Fix a constraint on number of channels.
 * ad7949
   - Fix an issue which can result in readouts being from the wrong channel.
 * hdc100x
   - Fix wrong ABI usage (units) for relative humidity channel.
 * intel mrfld
   - Allocate right amount of private data (currently allocating too much).
 * ltc2983
   - Avoid a potential issue with machine endianness and wrong length device
     tree read.
 * max1027
   - Clean up leak of an iio_trigger on probe failure.
 * max9611
   - Ensure we sleep long enough to successfully initialize the sensor.
 * mpu6050
   - Fix wrong ABI usage (units) for temperature channel.
 * st_accel
   - Fix an unused variable warning.
 * st_lsm6dsx
   - Fix decimation factor issue that can lead to missaligned datasets
     (and hence garbage)
   - Fix an issue with how we track enabled fifo channels.
   - Avoid powering off the device if wake up events are enabled.

Jonathan writes:

First set of fixes for IIO in the 5.5 cycle.

Mixture of old things people have just hit, and a few late breaking
issues with things that went in during the merge window.

Being sent promptly to resolve potential DT breakage causing
issues for binding test builds.

* ad7606
  - Avoid reading extra data from the device over what was intended.
* ad7124
  - Enable the internal reference when in use.
* ad7292
  - Fix up license for newly added binding.  Better to not have this go
    out in a release with more limited header than intended.
  - Fix a constraint on number of channels.
* ad7949
  - Fix an issue which can result in readouts being from the wrong channel.
* hdc100x
  - Fix wrong ABI usage (units) for relative humidity channel.
* intel mrfld
  - Allocate right amount of private data (currently allocating too much).
* ltc2983
  - Avoid a potential issue with machine endianness and wrong length device
    tree read.
* max1027
  - Clean up leak of an iio_trigger on probe failure.
* max9611
  - Ensure we sleep long enough to successfully initialize the sensor.
* mpu6050
  - Fix wrong ABI usage (units) for temperature channel.
* st_accel
  - Fix an unused variable warning.
* st_lsm6dsx
  - Fix decimation factor issue that can lead to missaligned datasets
    (and hence garbage)
  - Fix an issue with how we track enabled fifo channels.
  - Avoid powering off the device if wake up events are enabled.

43a2898631 powerpc updates for 5.5 #2 
A few commits splitting the KASAN instrumented bitops header in
 three, to match the split of the asm-generic bitops headers.
 
 This is needed on powerpc because we use asm-generic/bitops/non-atomic.h,
 for the non-atomic bitops, whereas the existing KASAN instrumented
 bitops assume all the underlying operations are provided by the arch
 as arch_foo() versions.

eec028c938 kcov: remote coverage support 
Patch series " kcov: collect coverage from usb and vhost", v3.

This patchset extends kcov to allow collecting coverage from backgound
kernel threads.  This extension requires custom annotations for each of
the places where coverage collection is desired.  This patchset
implements this for hub events in the USB subsystem and for vhost
workers.  See the first patch description for details about the kcov
extension.  The other two patches apply this kcov extension to USB and
vhost.

Examples of other subsystems that might potentially benefit from this
when custom annotations are added (the list is based on
process_one_work() callers for bugs recently reported by syzbot):

1. fs: writeback wb_workfn() worker,
2. net: addrconf_dad_work()/addrconf_verify_work() workers,
3. net: neigh_periodic_work() worker,
4. net/p9: p9_write_work()/p9_read_work() workers,
5. block: blk_mq_run_work_fn() worker.

These patches have been used to enable coverage-guided USB fuzzing with
syzkaller for the last few years, see the details here:

  https://github.com/google/syzkaller/blob/master/docs/linux/external_fuzzing_usb.md

This patchset has been pushed to the public Linux kernel Gerrit
instance:

  https://linux-review.googlesource.com/c/linux/kernel/git/torvalds/linux/+/1524

This patch (of 3):

Add background thread coverage collection ability to kcov.

With KCOV_ENABLE coverage is collected only for syscalls that are issued
from the current process.  With KCOV_REMOTE_ENABLE it's possible to
collect coverage for arbitrary parts of the kernel code, provided that
those parts are annotated with kcov_remote_start()/kcov_remote_stop().

This allows to collect coverage from two types of kernel background
threads: the global ones, that are spawned during kernel boot in a
limited number of instances (e.g.  one USB hub_event() worker thread is
spawned per USB HCD); and the local ones, that are spawned when a user
interacts with some kernel interface (e.g.  vhost workers).

To enable collecting coverage from a global background thread, a unique
global handle must be assigned and passed to the corresponding
kcov_remote_start() call.  Then a userspace process can pass a list of
such handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field
of the kcov_remote_arg struct.  This will attach the used kcov device to
the code sections, that are referenced by those handles.

Since there might be many local background threads spawned from
different userspace processes, we can't use a single global handle per
annotation.  Instead, the userspace process passes a non-zero handle
through the common_handle field of the kcov_remote_arg struct.  This
common handle gets saved to the kcov_handle field in the current
task_struct and needs to be passed to the newly spawned threads via
custom annotations.  Those threads should in turn be annotated with
kcov_remote_start()/kcov_remote_stop().

Internally kcov stores handles as u64 integers.  The top byte of a
handle is used to denote the id of a subsystem that this handle belongs
to, and the lower 4 bytes are used to denote the id of a thread instance
within that subsystem.  A reserved value 0 is used as a subsystem id for
common handles as they don't belong to a particular subsystem.  The
bytes 4-7 are currently reserved and must be zero.  In the future the
number of bytes used for the subsystem or handle ids might be increased.

When a particular userspace process collects coverage by via a common
handle, kcov will collect coverage for each code section that is
annotated to use the common handle obtained as kcov_handle from the
current task_struct.  However non common handles allow to collect
coverage selectively from different subsystems.

4f4afc2c95 docs/core-api: Remove possibly confusing sub-headings from Bit Operations 
The recent commit 81d2c6f819 ("kasan: support instrumented bitops
combined with generic bitops"), split the KASAN instrumented bitops
into separate headers for atomic, non-atomic and locking operations.

This was done to allow arches to include just the instrumented bitops
they need, while also using some of the generic bitops in
asm-generic/bitops (which are automatically instrumented). The generic
bitops are already split into atomic, non-atomic and locking headers.

This split required an update to kernel-api.rst because it included
include/asm-generic/bitops-instrumented.h, which no longer exists. So
now kernel-api.rst includes all three instrumented headers to get the
definitions for all the bitops.

When adding the three headers it seemed sensible to add sub-headings
for each, ie. "Atomic", "Non-atomic" and "Locking".

The confusion is that test_bit() is (and always has been) in
non-atomic.h, but is documented elsewhere (atomic_bitops.txt) as being
atomic. So having it appear under the "Non-atomic" heading is possibly
confusing.

Probably test_bit() should move from bitops/non-atomic.h to atomic.h,
but that has flow on effects. For now just remove the newly added
sub-headings in the documentation, so we at least aren't adding to the
confusion about whether test_bit() is atomic or not.

 "Most of the IRQ subsystem changes in this cycle were irq-chip driver
  updates:

   - Qualcomm PDC wakeup interrupt support

   - Layerscape external IRQ support

   - Broadcom bcm7038 PM and wakeup support

   - Ingenic driver cleanup and modernization

   - GICv3 ITS preparation for GICv4.1 updates

   - GICv4 fixes

  There's also the series from Frederic Weisbecker that fixes memory
  ordering bugs for the irq-work logic, whose primary fix is to turn
  work->irq_work.flags into an atomic variable and then convert the
  complex (and buggy) atomic_cmpxchg() loop in irq_work_claim() into a
  much simpler atomic_fetch_or() call.

  There are also various smaller cleanups"

 NCR5380, lpfc, qla2xxx, smartpqi, hisi_sas, target, mpt3sas, pm80xx
 plus a whole load of minor updates and fixes.  The two major core
 changes are Al Viro's reworking of sg's handling of copy to/from user,
 Ming Lei's removal of the host busy counter to avoid contention in the
 multiqueue case and Damien Le Moal's fixing of residual tracking
 across error handling.

  NCR5380, lpfc, qla2xxx, smartpqi, hisi_sas, target, mpt3sas, pm80xx
  plus a whole load of minor updates and fixes.

  The major core changes are Al Viro's reworking of sg's handling of
  copy to/from user, Ming Lei's removal of the host busy counter to
  avoid contention in the multiqueue case and Damien Le Moal's fixing of
  residual tracking across error handling"

937d6eefc7 Here's the main documentation changes for 5.5: 
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

1daa56bcfd IOMMU Updates for Linux v5.5 
Including:
 
 	- Conversion of the AMD IOMMU driver to use the dma-iommu code
 	  for imlementing the DMA-API. This gets rid of quite some code
 	  in the driver itself, but also has some potential for
 	  regressions (non are known at the moment).
 
 	- Support for the Qualcomm SMMUv2 implementation in the SDM845
 	  SoC.  This also includes some firmware interface changes, but
 	  those are acked by the respective maintainers.
 
 	- Preparatory work to support two distinct page-tables per
 	  domain in the ARM-SMMU driver
 
 	- Power management improvements for the ARM SMMUv2
 
 	- Custom PASID allocator support
 
 	- Multiple PCI DMA alias support for the AMD IOMMU driver
 
 	- Adaption of the Mediatek driver to the changed IO/TLB flush
 	  interface of the IOMMU core code.

Pull i2c updates from Wolfram Sang:
 "I2C has mostly driver updates this time.

  The few noteworthy changes are: the core has now support for analog
  and digital filters with at91 being the first user, a core addition to
  replace the NULL returning i2c_new_probed_device() with an ERR_PTR
  variant, and the pxa driver has finally being moved to use the generic
  I2C slave interface. We have quite a significant number of reviews per
  patch this time, so thank you to all involved!"
