3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arve Hjønnevåg <a...@android.com>
commit 585650dcec88e704a19bb226a34b6a7166111623 upstream.
The default kernel mapping for the pages allocated for the binder
buffers is never used. Set the __GFP_HIGHMEM flag when allocating
these pages so we don't needlessly use low memory pages that may
be required elsewhere.
