With further testing of recent changes with lockdep and other locking
checks enabled, we've found several bugs in the shrinker code and one
sleep while atomic in panfrost_gem_open(). This series addresses those 


Rob Herring (4):
  drm/shmem: Do dma_unmap_sg before purging pages
  drm/shmem: Use mutex_trylock in drm_gem_shmem_purge
  drm/panfrost: Fix shrinker lockdep issues using drm_gem_shmem_purge()
  drm/panfrost: Fix sleeping while atomic in panfrost_gem_open
