Commit 771d3feb authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'work.drm' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull DRM compat ioctl handling updates from Al Viro:
 "This kills the double-copies in there and tons of field-by-field
  copyin/copyout.

  Several dead ioctls put to rest, while we are at it - the native
  counterparts had been gone for a decade, so we can bloody well fail
  early on the compat side. No point rearranging the 32bit structure
  into 64bit one (and back) only to be told "piss off, I don't know that
  ioctl" by the native code..."

* 'work.drm' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (29 commits)
  Fix trivial misannotations
  mga: switch compat ioctls to drm_ioctl_kernel()
  radeon: take out dead compat ioctls
  drm compat: ia64 is not biarch
  drm_compat_ioctl(): tidy up a bit
  switch compat_drm_mapbufs() to drm_ioctl_kernel()
  switch compat_drm_rmmap() to drm_ioctl_kernel()
  switch compat_drm_mode_addfb2() to drm_ioctl_kernel()
  switch compat_drm_wait_vblank() to drm_ioctl_kernel()
  switch compat_drm_update_draw()
  compat_drm: switch sg ioctls
  compat_drm: switch AGP compat ioctls to drm_ioctl_kernel()
  switch compat_drm_dma() to drm_ioctl_kernel()
  switch compat_drm_resctx() to drm_ioctl_kernel()
