[PATCH 043/115] gpu: ion: Clear GFP_WAIT flag on high order allocations

From: Rebecca Schultz Zavin <rebecca@android.com>

This will prevent the kernel from kicking off compaction
when higher order allocations are made. Instead we will
get these high order allocations only if they are readily
available.
