Merge tag 'drm-misc-next-2018-09-13' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for 4.20:

UAPI Changes:
- Add host endian variants for the most common formats (Gerd)
- Fail ADDFB2 for big-endian drivers that don't advertise BE quirk (Gerd)
- clear smem_start in fbdev for drm drivers to avoid leaking fb addr (Daniel)

Cross-subsystem Changes:

Core Changes:
- fix drm_mode_addfb() on big endian machines (Gerd)
- add timeline point to syncobj find+replace (Chunming)
- more drmP.h removal effort (Daniel)
- split uapi portions of drm_atomic.c into drm_atomic_uapi.c (Daniel)

Driver Changes:
- bochs: Convert open-coded portions to use helpers (Peter)
- vkms: Add cursor support (Haneen)
- udmabuf: Lots of fixups (mostly cosmetic afaict) (Gerd)
- qxl: Convert to use fbdev helper (Peter)
