[PATCH v7 00/17] drm/msm: A couple lazy-vm fixes

[Rob Clark]

The VM is created lazily to give userspace a chance to opt-in to
VM_BIND.  But Sashiko noticed a couple paths that were not handling
this properly.  Or at least that is how this series started out.

Rob Clark (17):
  drm/msm: Fix barriers accessing ctx vm
  drm/msm: Rework queuelock
  drm/msm: Synchronize VM creation on ctxlock
  drm/msm: Synchronize set_sysprof on ctxlock
  drm/msm: Move nr_cmds initialization
  drm/msm: Remove redundant SIZE_MAX check
  drm/msm/a6xx: Access VM directly in submit path
  drm/msm: Add helper to check for per-process pgtables VM
  drm/msm/gem: Fix dma_buf import error paths
  drm/msm/gem: Remove useless locking in GEM import
  drm/msm/gem: Extract bookkeeping init helper
  drm/msm/gem: Set resv before exposing obj
  drm/msm/gem: Validate lazy VM in GEM_NEW
  drm/msm: Allow lazy VM creation to fail
  drm/msm: Don't fallback to shared VM for VM_BIND
  drm/msm: Fix per-process-pgtables check
  drm/msm: Fixup invalid overflow check
