SubjectRe: [PATCH] ANDROID: binder: remove 32-bit binder interface.

Looks like m68k doesn't support 64-bit get_user(). I could just have
binder depend on !CONFIG_M68K, but there may be other architectures
still that don't support this. Another alternative would be to
whitelist the architectures Android supports - eg arm, arm64, x86,
x86_64. But I'm not sure if arch-limited drivers are considered bad
form. Does anybody have suggestions for how to deal with this?
