cf401e2856 drm/amdkfd: fix null pointer dereference on dev 
The pointer dev is set to null yet it is being dereferenced when
checking dev->dqm->sched_policy.  Fix this by performing the check
on dev->dqm->sched_policy after dev has been assigned and null
checked.  Also remove the redundant null assignment to dev.

bec7550cca Merge tag 'docs-5.2-fixes2' of git://git.lwn.net/linux 
Pull documentation fixes from Jonathan Corbet:
 "The Sphinx 2.0 release contained a few incompatible API changes that
  broke our extensions and, thus, the documentation build in general.
  Who knew that those deprecation warnings it was outputting actually
  meant we should change something? This set of fixes makes the build
  work again with Sphinx 2.0 and eliminates the warnings for 1.8. As
  part of that, we also need a few fixes to the docs for places where
  the new Sphinx is more strict.

  It is a bit late in the cycle for this kind of change, but it does fix
  problems that people are experiencing now.

  There has been some talk of raising the minimum version of Sphinx we
  support. I don't want to do that abruptly, though, so these changes
  add some glue to continue to support versions back to 1.3. We will be
  adding some infrastructure soon to nudge users of old versions
  forward, with the idea of maybe increasing our minimum version (and
  removing this glue) sometime in the future"

7f5f228008 drm/i915/gtt: Avoid overflowing the WC stash 
An interesting issue cropped with making the pagetables be allocated and
freed concurrently (i.e. removing their grandeous struct_mutex guard)
was that we would overflow the page stash. This happens when we have
multiple allocators grabbing WC pages such that we fill the vm's local
page stash and then when we free another page, the page stash is already
full and we overflow.

The fix is quite simple: to check for a full page stash before adding
another. This results in us keeping a vm local page stash around for
much longer, which is both a blessing and a curse.

a10f361d17 Revert "drm/i915: Expand subslice mask" 
This reverts commit 1ac159e23c ("drm/i915: Expand subslice mask"),
which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a
chance to do anything.

The commit exposes an issue in commit 1e40d4aea5 ("drm/i915/cnl:
Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will
also need to be addressed.

There's a proposed fix [1], but considering the seeming uncertainty with
the fix as well as the size of the regressing commit (in this context,
the one that actually brings down ICL), this warrants a revert to get
ICL working, and gives us time to get all of this right without
rushing. Even if this means shooting the messenger.

0c1f845772 drm/i915: Avoid refcount_inc on known zero count 
In intel_wakeref_auto, we use refcount_inc_not_zero to detect the first
use and initialise the timer. On doing so, we have to avoid using
refcount_inc on that zero count as the debug code flags that as an
error:
	refcount_t: increment on 0; use-after-free.

Rearrange the code so that if we know the count is 0 and we are
initialising, we explicitly set it to 1.
