Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
From: Lucas Stach <l.stach@pengutronix.de>
"not much to de-stage this time. Changes from Philipp and Souptick to
use memset32 more and switch the fault handler to the new vm_fault_t
and two small fixes for issues that can be hit in rare corner cases
from me."
