commit: 585650dcec88e704a19bb226a34b6a7166111623 From: =?UTF-8?q?Arve=20Hj=C3=B8nnev=C3=A5g?= <[email protected]> Date: Tue, 16 Oct 2012 15:29:55 -0700 Subject: Staging: android: binder: Allow using highmem for binder buffers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
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.
