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 let ANDROID_BINDER_IPC_32BIT be selectable on
32bit ARM  

Ok, but:

You don't actually change the depends line :(

Please fix up, and test it, and then resend.

IHOM, the dependency is correct: 64bit platforms don't support
ANDROID_BINDER_IPC_32BIT. What do you think?

Thanks,
