[Intel-gfx] [PULL] drm-intel-fixes

Hi Dave & Daniel,

Another -rc, another CI fire due to regressions elsewhere.

Our CI needed the following patches to get machines boot with -rc2:

	Revert "devtmpfs: use do_mount() instead of ksys_mount()"
	(commit 5e787dbf659fe77d56215be74044f85e01b3920f)

	Revert "initrd: use do_mount() instead of ksys_mount()"
	(commit d4440aac83d12f87df9bcc51e992b9c28c7f4fa5)

	Revert "init: use do_mount() instead of ksys_mount()"
	(commit cccaa5e33525fc07f4a2ce0518e50b9ddf435e47)

I have queued CI_DIF_433 with this PR contents + reverts to get any
CI results:

https://intel-gfx-ci.01.org/tree/drm-intel-fixes/CI_DIF_433/git-log.txt

Nothing appears in the UI for the failed-to-boot runs, so don't be
confused. CI_DIF_433 is equal to this PR + 3 reverts needed to mitigate
the -rc2 regressions.

Due to the CI fires, it may take a while to get the full results. Due to
my holidays, I'll defer to Chris to let you know if the results are good
or not. There have been some GEM bugs tackled in drm-tip, so have to make
sure they are under control.

Now on to the actual content of the PR:

Removal of a unused and harmful display W/A for Tigerlake, corrections
to powerwells of EHL compared to ICL, and MMIO offset fix for DSB. There
is a fix for uninitialized ops in dma_fence tracing and then fixes
for CI corner cases from CI.

Also includes GVT fixes: "fix for vGPU display dmabuf, one guest reset
warning and one locking issue."

Jani/Rodrigo promised to handle -fixes for next two weeks if there is
something urgent appearing.

Happy Holidays!

Regards, Joonas
