In do_notify_resume, we manipulate thread_flags as a 32-bit unsigned
int, whereas thread_info::flags is a 64-bit unsigned long, and elsewhere
(e.g. in the entry assembly) we manipulate the flags as a 64-bit
quantity.

For consistency, and to avoid problems if we end up with more than 32
flags, let's make do_notify_resume take the flags as a 64-bit unsigned
long.

When we get to more than 32 flags, you may want to modify the _TIF_*
definitions as well to (UL(1) << TIF_*).

Agreed. I can spin a patch or two for a that as a subsequent cleanup.
