This is a note to let you know that I've just added the patch titled
Staging: android: binder: Allow using highmem for binder buffers
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

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.
