  I just got time to have a closer look on the uffd-wp triggering of the
warning here:

https://lore.kernel.org/all/YzeR+R6b4bwBlBHh@x1n/T/#u

It turns out to be a wrong check on vma, and with the fix attached we
should be able to remove the ugly macro checks.  Sorry for the bothersome.

Please have a look, thanks.
