I don't know if you want the default to be y. By the time this kernel
is used, the user-space default may have switched to using the 64 bit
interface by default. The android-3.10 kernel currently defaulting to
y since it may get used with a 4.4 android user-space, and because the
32 bit arm kernel is missing the 8 byte get_user variant that it
needs.
