linux-next: build failure after merge of the akpm-current tree

Hi all,

After merging the akpm-current tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/i915/i915_gem_execbuffer.c: In function 'get_fence_array':
drivers/gpu/drm/i915/i915_gem_execbuffer.c:2163:20: error: 'GFP_TEMPORARY' undeclared (first use in this function)
__GFP_NOWARN | GFP_TEMPORARY);
^

Caused by commit

4d6fc0a48c52 ("mm: treewide: remove GFP_TEMPORARY allocation flag")

interacting with commit

cf6e7bac6357 ("drm/i915: Add support for drm syncobjs")

from the drm-intel tree.

I applied the following merge fix patch (and I suspect - given the
comments in the former commit message - that this could be applied to
the drm-intel tree right now without any problems):
