[v2,0/7] drm/ttm: Small fixes / cleanups in prep for shrinking

Message

I collected the, from my POW, uncontroversial patches from V1 of the TTM
shrinker series, some corrected after the initial patch submission, one
patch added from the Xe RFC ("drm/ttm: Don't print error message if
eviction was interrupted"). It would be nice to have these reviewed and
merged while reworking the rest.

v2:
- Simplify __ttm_pool_free().
- Fix the TTM_TT_FLAG bit numbers.
- Keep all allocation orders for TTM pages at or below PMD order

Thomas Hellström (7):
  drm/ttm: Fix a NULL pointer dereference
  drm/ttm/pool: Fix ttm_pool_alloc error path
  drm/ttm: Use the BIT macro for the TTM_TT_FLAGs
  drm/ttm: Unexport ttm_global_swapout()
  drm/ttm: Don't print error message if eviction was interrupted
  drm/ttm: Reduce the number of used allocation orders for TTM pages
  drm/ttm: Make the call to ttm_tt_populate() interruptible when
    faulting
