Add a KUnit test for the kernel doubly linked list implementation in
include/linux/list.h
Each test case (list_test_x) is focused on testing the behaviour of the
list function/macro 'x'. None of the tests pass invalid lists to these
macros, and so should behave identically with DEBUG_LIST enabled and
disabled.
Note that, at present, it only tests the list_ types (not the
singly-linked hlist_), and does not yet test all of the
list_for_each_entry* macros (and some related things like
list_prepare_entry).
Ignoring checkpatch.pl spurious errors related to its handling of for_each
and other list macros. checkpatch.pl expects anything with for_each in its
name to be a loop and expects that the open brace is placed on the same
line as for a for loop. In this case, test case naming scheme includes
name of the macro it is testing, which results in the spurious errors.

Pull arm64 fixes from Will Deacon:
"These are almost exclusively related to CPU errata in CPUs from
Broadcom and Qualcomm where the workarounds were either not being
enabled when they should have been or enabled when they shouldn't have
been.
The only "interesting" fix is ensuring that writeable, shared mappings
are initially mapped as clean since we inadvertently broke the logic
back in v4.14 and then noticed the problem via code inspection the
other day.
The only critical issue we have outstanding is a sporadic NULL
dereference in the scheduler, which doesn't appear to be
arm64-specific and PeterZ is tearing his hair out over it at the
moment.

When games, browser, or anything using a lot of GPU buffers exits, there
can be many hundreds or thousands of buffers to unmap and free. If the
GPU is otherwise suspended, this can cause arm-smmu to resume/suspend
for each buffer, resulting 5-10 seconds worth of reprogramming the
context bank (arm_smmu_write_context_bank()/arm_smmu_write_s2cr()/etc).
To the user it would appear that the system just locked up.
A simple solution is to use pm_runtime_put_autosuspend() instead, so we
don't immediately suspend the SMMU device.

Currently we shutdown rc6 during i915_gem_resume() but this is called
during the preparation phase (i915_drm_prepare) for all suspend paths,
but we only want to shutdown rc6 for S3+. Move the actual shutdown to
i915_gem_suspend_late().
We then need to differentiate between suspend targets, to distinguish S0
(s2idle) where the device is kept awake but needs to be in a low power
mode (the same as runtime suspend) from the device suspend levels where
we lose control of HW and so must disable any HW access to dangling
memory.

Currently, if the loop device receives a WRITE_ZEROES request, it asks
the underlying filesystem to punch out the range. This behavior is
correct if unmapping is allowed. However, a NOUNMAP request means that
the caller doesn't want us to free the storage backing the range, so
punching out the range is incorrect behavior.
To satisfy a NOUNMAP | WRITE_ZEROES request, loop should ask the
underlying filesystem to FALLOC_FL_ZERO_RANGE, which is (according to
the fallocate documentation) required to ensure that the entire range is
backed by real storage, which suffices for our purposes.

This adds support for IORING_OP_ASYNC_CANCEL, which will attempt to
cancel requests that have been punted to async context and are now
in-flight. This works for regular read/write requests to files, as
long as they haven't been started yet. For socket based IO (or things
like accept4(2)), we can cancel work that is already running as well.
To cancel a request, the sqe must have ->addr set to the user_data of
the request it wishes to cancel. If the request is cancelled
successfully, the original request is completed with -ECANCELED
and the cancel request is completed with a result of 0. If the
request was already running, the original may or may not complete
in error. The cancel request will complete with -EALREADY for that
case. And finally, if the request to cancel wasn't found, the cancel
request is completed with -ENOENT.

Now that we split plane_state which I didn't want to do yet, we can
program the slave plane without requiring the master plane.
This is useful for programming bigjoiner slave planes as well. We
will no longer need the master's plane_state.
Changes since v1:
- set src/dst rectangles after copy_uapi_to_hw_state.
Changes since v2:
- Use the correct color_plane for pre-gen11 by using planar_linked_plane != NULL.
- Use drm_format_info_is_yuv_semiplanar in skl_plane_check() to fix gen11+.

Splitting plane state is easier than splitting crtc_state,
before plane check we copy the drm properties to hw so we can
do the same in bigjoiner later on.
We copy the state after we did all the modeset handling, but fortunately

at plane_state.

Now that we separated everything into uapi and hw, it's

before color management is checked.

- Clear crtc_state->hw on disable, instead of using clear_intel_crtc_state().
Changes since v2:
- Use intel_crtc_free_hw_state + clear in intel_crtc_disable_noatomic().
- Make a intel_crtc_prepare_state() function that clears the crtc_state

- Remove setting uapi.adjusted_mode, we now have a direct call to

Add support for the power areas in the Renesas R-Car M3-W+ (R8A77961)
SoC to the R-Car System Controller driver.
R-Car M3-W+ (aka R-Car M3-W ES3.0) is very similar to R-Car
M3-W (R8A77960), which allows for both SoCs to share a driver:
- R-Car M3-W+ lacks the A2VC power area, so its area must be
nullified,
- The existing support for the SYSCEXTMASK register added in commit
9bd645af9d2a49ac ("soc: renesas: r8a7796-sysc: Fix power request
conflicts") applies to ES3.0 and later only.
As R-Car M3-W+ uses a different compatible value, differentiate
based on that, instead of on the ES version.
