[PATCH 00/12] v3d: Perfmon cleanup

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at igalia.com>

When we had to quickly deal with a tree build issue via merging
792d16b5375d ("drm/v3d: Move perfmon init completely into own unit"), we
promised to follow up with a nicer solution.

As in the process of eliminating the hardcoded defines we have discovered a few
issues in handling of corner cases and userspace input validation, the fix has
turned into a larger series, but hopefully the end result is a justifiable
cleanup.

Tvrtko Ursulin (12):
  drm/v3d: Prevent out of bounds access in performance query extensions
  drm/v3d: Prefer get_user for scalar types
  drm/v3d: Add some local variables in queries/extensions
  drm/v3d: Align data types of internal and uapi counts
  drm/v3d: Fix potential memory leak in the timestamp extension
  drm/v3d: Fix potential memory leak in the performance extension
  drm/v3d: Validate passed in drm syncobj handles in the timestamp
    extension
  drm/v3d: Validate passed in drm syncobj handles in the performance
    extension
  drm/v3d: Move part of copying of reset/copy performance extension to a
    helper
  drm/v3d: Size the kperfmon_ids array at runtime
  drm/v3d: Do not use intermediate storage when copying performance
    query results
  drm/v3d: Move perfmon init completely into own unit
