Subject: [PATCH] drm/msm: Fix build break with recent mm tree

9178e3dcb121 ("mm: discard __GFP_ATOMIC") removed __GFP_ATOMIC,
replacing it with a check for not __GFP_DIRECT_RECLAIM.

Sorry, this was reported by Stephen earlier in the month, while
I was on the other side of the globe and jetlagged.  Unfortunately
I forgot about it by the time I got back home.  Applying this patch
after 025d27239a2f ("drm/msm/gem: Evict active GEM objects when necessary")
but before or after 9178e3dcb121 ("mm: discard __GFP_ATOMIC") should
resolve the build breakage.
