I don't think this is correct on all 64-bit architectures, as far as I
remember the
definition can use either 'long' or 'long long' depending on the user space
toolchain.
Out of the ten supported 64-bit architectures, there are four that already
use asm-generic/int-l64.h conditionally, and six that don't, and I
think at least
some of those are intentional.
I think it would be safer to do this one architecture at a time to make
sure this doesn't regress on those that require the int-ll64.h version.
There should also be a check for __SANE_USERSPACE_TYPES__
to let userspace ask for the ll64 version everywhere.
