This patch set fixes the binder interface so that it works on 32/32 or
64/64 systems and preps the driver for the compat layer - 64bit
kernel/32bit userspace. As discussed with the Android developers the
binder compat will live in the userspace. Thus for a 64bit kernel the
calls coming from 32 or 64bit file-systems will look alike.
Thus for the moment it won't work.
Thanks,
Serban
