Staging: android: binder: Allow using highmem for binder buffers
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.
