Subject: drm/ttm: Fix cached TTM page allocation.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e8613c0e29d0018a80652e6ae58660c8a75ac74b;p=deliverable%2Flinux.git

drm/ttm: Fix cached TTM page allocation.

This patch fixes a regression introduced with the pool page allocator
in the event that there are no highmem pages (for example x86_64),
in which case cached page allocation would fail.

Tested with the vmwgfx driver on a 64-bit vm.
