Obviously my patch has the opposite problem: 64-bit wrap-arounds.
I know you alluded to a case in another thread, but I couldn't quite
work out from the mail you referred to whether this was really the
problem. (And I assume those folks were forced to fix their set-up
scripts anyway.) So, it's not clear to me whether this is a real
problem. (And your patch does not worsen things from the current
situation, right?)
a) When I wrote the comment it was just an idea.
But now I think wrap-around could be an issue, e.g.
find_vma_intersection(,addr,addr+ULONG_MAX) always returns false, even
if there are vmas inbetween.
b) If we make ULONG_MAX the default, then it should work.
