[Intel-gfx] [PATCH v2 0/6] drm/atomic: Interruptible locks for everyone!

drm_atomic_commit could previous have always failed when waits failed,
but locking was always done uninterruptibly. Add infrastructure to make
it possible for callers to choose interruptible locking, and convert the
5 most common ioctl's to use it.

All other atomic helpers can be converted when additional tests are added
to kms_atomic_interruptible.

Changes since last version:
- Small fixes to the preparation patch
- Convert setcrtc as well.

Maarten Lankhorst (6):
  drm/atomic: Prepare drm_modeset_lock infrastructure for interruptible
    waiting, v2.
  drm/atomic: Convert atomic ioctl locking to interruptible.
  drm/legacy: Convert cursor ioctl locking to interruptible.
  drm/legacy: Convert setplane ioctl locking to interruptible.
  drm/atomic: Convert pageflip ioctl locking to interruptible.
  drm/crtc: Convert setcrtc ioctl locking to interruptible.
