drm/nouveau/devinit/gf100: make devinit on resume safer
In case of successful suspend, devinit will have to be run and this is
the behavior currently hardcoded. However, as FD bug 94725 suggests,
there might be cases where runtime suspend leaves the GPU powered, and
in such cases devinit should not be run on resume.
On GF100+ we have a reliable way to know whether we need to run devinit.
Use it instead of blindly trusting the flag set by nvkm_devinit_fini().
The code around the NvForcePost also needs to be slightly reworked in
order to keep working.

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-next' of git://git.pengutronix.de:/git/lst/linux:
drm/etnaviv: fix mmap operations for userptr and dma-buf objects
drm/etnaviv: take etnaviv_gem_obj in etnaviv_gem_mmap_obj
drm/etnaviv: use deferrable timer for hangcheck handler
timer: add setup_deferrable_timer macro
