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
