20fd600099 drm/i915/guc: fix GuC suspend/resume 
The ENTER/EXIT_S_STATE actions queue the save/restore operation in GuC
FW and then return, so waiting on the H2G is not enough to guarantee
GuC is done.
When all the processing is done, GuC writes 0 to scratch register 14,
so we can poll on that. Note that GuC does not ensure that the value
in the register is different from 0 while the action is in progress
so we need to take care of that ourselves as well.

v2: improve comment, return early on GuC error and improve error
    message (Michal)

0e8afefd5d drm: panel-orientation-quirks: Add quirk for Acer One 10 (S1003) 
The Acer One 10 uses a clamshell design with a detachable keyboard.
As such in normal operating mode, with the keyboard attach the device
is in landscape mode (and the Acer logo at boot also shows in landscape
mode).

But the device uses a portrait screen rotated 90 degrees (sigh). This
commit adds a quirk for this device so that we shown the fbcon the
right way up and that we hint userspace to also show e.g. plymouth and
gdm the right way up.

914a4fd8cd drm/i915/gen9+: Fix initial readout for Y tiled framebuffers 
If BIOS configured a Y tiled FB we failed to set up the backing object
tiling accordingly, leading to a lack of GT fence installed and a
garbled console.

The problem was bisected to
commit 011f22eb54 ("drm/i915: Do NOT skip the first 4k of stolen memory for pre-allocated buffers v2")
but it just revealed a pre-existing issue.

Kudos to Ville who suspected a missing fence looking at the corruption
on the screen.

a378050989 drm/bufs: Fix Spectre v1 vulnerability 
idx can be indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.

This issue was detected with the help of Smatch:

drivers/gpu/drm/drm_bufs.c:1420 drm_legacy_freebufs() warn: potential
spectre issue 'dma->buflist' [r] (local cap)

Fix this by sanitizing idx before using it to index dma->buflist

Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

410ed5731a drm/i915: Ensure intel_engine_init_execlist() builds with Clang 
Clang build with UBSAN enabled leads to the following build error:

drivers/gpu/drm/i915/intel_engine_cs.o: In function `intel_engine_init_execlist':
drivers/gpu/drm/i915/intel_engine_cs.c:411: undefined reference to `__compiletime_assert_411'

Again, for this to work the code would first need to be inlined and then
constant folded, which doesn't work for Clang because semantic analysis
happens before optimization/inlining.

Use GEM_BUG_ON() instead of BUILD_BUG_ON().

v2: Use is_power_of_2() from log2.h (Chris)

7b3e51dd43 drm/i915: Ensure _print_param() builds with Clang 
When building the kernel with Clang with defconfig and CONFIG_64BIT
disabled, vmlinux fails to link because of the BUILD_BUG in
_print_param.

ld: drivers/gpu/drm/i915/i915_params.o: in function `i915_params_dump':
i915_params.c:(.text+0x56): undefined reference to
`__compiletime_assert_191'

This function is semantically invalid unless the code is first inlined
then constant folded, which doesn't work for Clang because semantic
analysis happens before optimization/inlining.

[The above written by Nathan Chancellor <natechancellor@gmail.com>]

Use WARN_ONCE() instead of BUILD_BUG() to avoid the problem. The
WARN_ONCE() should get optimized away unless there's a type that's not
handled by _print_param().

d344b21bf4 drm/amd/amdgpu: Fix debugfs error handling 
The error handling is wrong and "ent" could be NULL we when dereference
it to get "ent->d_inode".

The thing is that normally debugfs_create_file() is not supposed to
require (or have) any error handling.  That function does return error
pointers if debugfs is turned off but we know it's enable here.  When
it's enabled, then it returns NULL on error.

So what I did was I stripped out all the error handling except around
the i_size_write().  I could have just used a NULL check instead of an
IS_ERR_OR_NULL() but I figured this was more clear because that way you
don't have to look at the surrounding code to see whether debugfs is
enabled or not.

4207c8b991 drm/i915: Always read out M2_N2 in intel_cpu_transcoder_get_m_n, v2. 
has_drrs is a flag we can't read out. We set it when seamless DRRS is
enabled in pipe_config, so intel_dump_pipe_config() and
intel_pipe_config_compare() will continue to do the right thing when
has_drrs is set on the real state.

This removes one more dereference of crtc->config.
While at it, fixup the comment and also read out M2_N2 for CHV, since
we program it in the set_m_n function.

Changes since v1:
- Only read out M2/N2 on platforms that support DRRS.

This will close a race where we get a level indication between

could have avoided one.

Further, as the reading acts also as a post, replace the
write/post on the irq reset with the helper. On enabling side,
posting doesn't serve any purpose so it can also be replaced
with helper.

43c3ff27a4 drm/amd/display: fix bug of accessing invalid memory 
[Why]
A loop inside of build_evenly_distributed_points function that traverse through
the array of points become an infinite loop when m_GammaUpdates does not
get assigned to any value.

[How]
In DMColor, clear m_gammaIsValid bit just before writting all Zeromem for
m_GammaUpdates, to prevent calling build_evenly_distributed_points
before m_GammaUpdates gets assigned to some value.
