drm/vmwgfx: Kill some lockdep warnings
Some global KMS state that is elsewhere protected by the mode_config
mutex here needs to be protected with a local mutex. Remove corresponding
lockdep checks and introduce a new driver-private global_kms_state_mutex,
and make sure its locking order is *after* the crtc locks in order to
avoid having to release those when the new mutex is taken.

drm/exynos/decon5433: handle vblank in vblank interrupt
vblank should be signaled to userspace after reading framebuffers not before,
signaling it in TE interrupt looks wrong. TE triggers reading framebuffers
so it is the worst moment. Tearing is not observable because hardware prevents
it, but there are frequently skipped vblank events.

Merge branch 'drm-etnaviv-next' of git://git.pengutronix.de:/git/lst/linux into drm-next
not much new stuff this time. A (micro-)optimization to allow the
hangcheck timer to be coalesced with other wakeups in the system and a
fix to handle mmaping of prime imported and userptr buffers correctly. I
don't think we have seen any actual issues going back to this yet, so I
figured it's safer to get this in via drm-next rather than smashing it
into fixes.

drm/etnaviv: fix mmap operations for userptr and dma-buf objects
