This patch set has been successfully tested on 32bit platforms(ARMv7 VExpress)
and 64bit platforms(ARMv8 RTSM) running a 32bit Android userspace and an in
kernel binder compat layer.
I've tried to replace ugly hack with your patches to be able to boot
32-bit userspace on x86-64. It fails. :(
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.
Does the compat layer already exist or it's a plan?
