      drm: convert drm_ioctl to unlocked_ioctl · ed8b6704
      Arnd Bergmann authored
      drm_ioctl is called with the Big Kernel Lock held,
      which shows up very high in statistics on vfs_ioctl.
      Moving the lock into the drm_ioctl function itself
      makes sure we blame the right subsystem and it gets
      us one step closer to eliminating the locked version
      of fops->ioctl.
      Since drm_ioctl does not require the lock itself,
      we only need to hold it while calling the specific
      handler. The 32 bit conversion handlers do not
      interact with any other code, so they don't need
      the BKL here either and can just call drm_ioctl.
      As a bonus, this cleans up all the other users
      of drm_ioctl which now no longer have to find
      the inode or call lock_kernel.
      [airlied: squashed the non-driver bits
      of the second patch in here, this provides
      the flag for drivers to use to select unlocked
      ioctls - but doesn't modify any drivers].
