Subject: [PATCH 0/2] staging: android: ashmem: add 32bit compat support

Hi all,

This set of patches will add support for existing 32bit Android ashmem
syscalls on 64bit platforms. They also fix the ashmem pin/unpin interface
without affecting the 32bit ABI but imposing a new, correct one, for any
future 64bit Android userspace.

They have been successfully tested on 32bit platforms(VExpress 4xA9) and
64bit platforms(RTSMv8) running 32bit Android userspace and 64bit Linux +
ashmem unit tests.

Best Regards,
Serban Constantinescu
PDSW Engineer ARM Ltd.
