Subject: [PATCH] Staging: android: binder: Allow using highmem for binder
buffers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
