Subject: [PATCH v2] binder: allow ANDROID_BINDER_IPC_32BIT to be unselected on 32bit ARM

As noted in commit d0bdff0db809 ("staging: Fix build issues with new
binder API"), we can add back the choice for 32bit ARM "once a 64bit
__get_user_asm_* implementation is merged." Commit e38361d032f1 ("ARM:
8091/2: add get_user() support for 8 byte types") has added the
support, so it's time to allow ANDROID_BINDER_IPC_32BIT to be
unselected on 32bit ARM so that the 64bit ABI can be tested/used on
32bit systems.

This change allows running the same 32bit userspace build no matter
the kernel is 64bit or 32bit.

Again, your changelog text does not match up with what this patch does
at all, please fix something...
