Subject: [PATCH] libdrm: Use mmap64 instead of __mmap2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

__mmap2 isn't supported on all platforms, mmap64 is the right way
to do this in android.

Also folds in a fix from Stéphane Marchesin <marcheu@chromium.org>
