Gaah. That sounds really familiar. Have we done this same mistake once
before already, or is it just deja-vu for some other reason.

On x86-64 UML, we have

#define VM_STACK_DEFAULT_FLAGS vm_stack_flags

so VM_STACK_FLAGS ends up not being a constant, even though it really
looks like one.

UML is _really_ confused in this area, btw. It seems to re-define that
thing if TIF_IA32 is defined. That's some crazy stuff. Doesn't the
compiler warn about it?

I guess I should just revert that commit, though. Even if it does seem
to be the case that UML is just being crazy. Andrew?
