A previous commit enabled execlists by default:

       commit 27401d12 ("drm/i915/bdw: Enable execlists by default where supported")

This allowed routine testing of execlists which exposed a regression when
resuming from suspend.  The cause was tracked down the to recent changes to the
ring init sequence:

       commit 35a57ffb ("drm/i915: Only init engines once")

During a suspend/resume cycle the hardware Context Status Buffer write pointer
is reset.  However since the recent changes to the init sequence the software CSB
read pointer is no longer reset.  This means that context status events are not
handled correctly and new contexts are not written to the ELSP, resulting in an
apparent GPU hang.

Pending further changes to the ring init code, just move the
ring->next_context_status_buffer initialization into gen8_init_common_ring to
fix this regression.

v2: Moved init into gen8_init_common_ring rather than context_enable after
feedback from Daniel Vetter.  Updated commit msg to reflect this and also cite
commits related to the regression.  Fixed bz link to correct bug.

The userspace-requested plane coordinates are now always available via
plane->state.base (and the i915-adjusted values are stored in
plane->state), so we no longer use the coordinate fields in intel_plane
and can drop them.

Also, note that the error case for pageflip calls update_plane() to
program the values from plane->state; it's simpler to just call
intel_plane_restore() which does the same thing.

v2: Replace manual update_plane() with intel_plane_restore() in pageflip
    error handler.

Switch plane handling to use the atomic plane helpers.  This means that
rather than provide our own implementations of .update_plane() and
.disable_plane(), we expose the lower-level check/prepare/commit/cleanup
entrypoints and let the DRM core implement update/disable for us using
those entrypoints.

The other main change that falls out of this patch is that our
drm_plane's will now always have a valid plane->state that contains the
relevant plane state (initial state is allocated at plane creation).
The base drm_plane_state pointed to holds the requested source/dest
coordinates, and the subclassed intel_plane_state holds the adjusted
values that our driver actually uses.

v2:
 - Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel)
 - Fix a copy/paste comment mistake (Bob)

v3:
 - Use prepare/cleanup functions that we've already factored out
 - Use newly refactored pre_commit/commit/post_commit to avoid sleeping
   during vblank evasion

v4:
 - Rebase to latest di-nightly requires adding an 'old_state' parameter
   to atomic_update;

v5:
 - Must have botched a rebase somewhere and lost some work.  Restore
   state 'dirty' flag to let begin/end code know which planes to
   run the pre_commit/post_commit hooks for.  This would have actually
   shown up as broken in the next commit rather than this one.

v6:
 - Squash kerneldoc patch into this one.
 - Previous patches have now already taken care of most of the
   infrastructure that used to be in this patch.  All we're adding here
   now is some thin wrappers.

v7:
 - Check return of intel_plane_duplicate_state() for allocation
   failures.

v8:
 - Drop unused drm_plane_state -> intel_plane_state cast.  (Ander)
 - Squash in actual transition to plane helpers.  Significant
   refactoring earlier in the patchset has made the combined
   prep+transition much easier to swallow than it was in earlier
   iterations. (Ander)

v9:
 - s/track_fbs/disabled_planes/ in the atomic crtc flags.  The only fb's
   we need to update frontbuffer tracking for are those on a plane about
   to be disabled (since the atomic helpers never call prepare_fb() when
   disabling a plane), so the new name more accurately describes what
   we're actually tracking.

A few of the sprite-related function names in i915 are very similar
(e.g., intel_enable_planes() vs intel_crtc_enable_planes()) and don't
make it clear whether they only operate on sprite planes, or whether
they also apply to all universal plane types.  Rename a few functions to
be more consistent with our function naming for primary/cursor planes or
to clarify that they apply specifically to sprite planes:

 - s/intel_disable_planes/intel_disable_sprite_planes/
 - s/intel_enable_planes/intel_enable_sprite_planes/

Also, drop the sprite-specific intel_destroy_plane() and just use
the type-agnostic intel_plane_destroy() function.  The extra 'disable'
call that intel_destroy_plane() did is unnecessary since the plane will
already be disabled due to framebuffer destruction by the point it gets
called.

v2: Earlier consolidation patches have reduced the number of functions
    we need to rename here.

v3: Also rename intel_plane_funcs vtable to intel_sprite_plane_funcs
    for consistency with primary/cursor.  (Ander)

    is no longer a static function.  (Ander)

Move the vblank evasion up from the low-level, hw-specific
update_plane() handlers to the general plane commit operation.
Everything inside commit should now be non-sleeping, so this brings us

v2:
 - Restore lost intel_crtc->active check on vblank evasion

v3:
 - Replace assert_pipe_enabled() in intel_disable_primary_hw_plane()
   with an intel_crtc->active test; it turns out assert_pipe_enabled()
   grabs some mutexes and can sleep, which we can't do with interrupts
   disabled.

Once we integrate our work into the atomic pipeline, plane commit
operations will need to happen with interrupts disabled, due to vblank
evasion.  Our commit functions today include sleepable work, so those
operations need to be split out and run either before or after the
atomic register programming.

The solution here calculates which of those operations will need to be
performed during the 'check' phase and sets flags in an intel_crtc
sub-struct.  New intel_begin_crtc_commit() and
intel_finish_crtc_commit() functions are added before and after the
actual register programming; these will eventually be called from the
atomic plane helper's .atomic_begin() and .atomic_end() entrypoints.

v2: Fix broken sprite code split

v3: Make the pre/post commit work crtc-based to match how we eventually
    want this to be called from the atomic plane helpers.

v4: Some platforms that haven't had their watermark code reworked were
    waiting for vblank, then calling update_sprite_watermarks in their
    platform-specific disable code.  These also need to be flagged out
    of the critical section.

v5: Sprite plane test for primary show/hide should just set the flag to
    wait for pending flips, not actually perform the wait.  (Ander)

v6:
 - Rebase onto latest di-nightly; picks up an important runtime PM fix.
 - Handle 'wait_for_flips' flag in intel_begin_crtc_commit(). (Ander)
 - Use wait_for_flips flag for primary plane update rather than
   performing the wait in the check routine.
 - Added kerneldoc to pre_disable/post_enable functions that are no
   longer static.  (Ander)
 - Replace assert_pipe_enabled() in intel_disable_primary_hw_plane()
   with an intel_crtc->active test; it turns out assert_pipe_enabled()
   grabs some mutexes and can sleep, which we can't do with interrupts
   disabled.

v7:
 - Check for fb != NULL when deciding whether the sprite plane hides the
   primary plane during a sprite update.  (PRTS)

Fix for BUG_ON(anon_vma->degree) splashes in unlink_anon_vmas() ("kernel
BUG at mm/rmap.c:399!") caused by commit 7a3ef208 ("mm: prevent
endless growth of anon_vma hierarchy")

Anon_vma_clone() is usually called for a copy of source vma in
destination argument.  If source vma has anon_vma it should be already
in dst->anon_vma.  NULL in dst->anon_vma is used as a sign that it's
called from anon_vma_fork().  In this case anon_vma_clone() finds
anon_vma for reusing.

Vma_adjust() calls it differently and this breaks anon_vma reusing
logic: anon_vma_clone() links vma to old anon_vma and updates degree
counters but vma_adjust() overrides vma->anon_vma right after that.  As
a result final unlink_anon_vmas() decrements degree for wrong anon_vma.

This patch assigns ->anon_vma before calling anon_vma_clone().

Commit fee7e49d ("mm: propagate error from stack expansion even for
guard page") made sure that we return the error properly for stack
growth conditions.  It also theorized that counting the guard page
towards the stack limit might break something, but also said "Let's see
if anybody notices".

Somebody did notice.  Apparently android-x86 sets the stack limit very
close to the limit indeed, and including the guard page in the rlimit
check causes the android 'zygote' process problems.

So this adds the (fairly trivial) code to make the stack rlimit check be
against the actual real stack size, rather than the size of the vma that
includes the guard page.

Pull drm fixes from Dave Airlie:
 "I'm briefly working between holidays and LCA, so this is close to a
  couple of weeks of fixes,

  Two sets of amdkfd fixes, this is a new feature this kernel, and this
  pull fixes a few issues since it got merged, ordering when built-in to
  kernel and also the iommu vs gpu ordering patch, it also reworks the
  ioctl before the initial release.

  Otherwise:
   - radeon: some misc fixes all over, hdmi, 4k, dpm
   - nouveau: mcp77 init fixes, oops fix, bug on fix, msi fix
   - i915: power fixes, revert VGACNTR patch

  Probably be quiteer next week since I'll be at LCA anyways"
