I grabbed these and built them.  Only change needed was another include.
After that, everything built fine and xpmem regression tests ran through
the first four sets.  The fifth is the oversubscription test which trips
my xpmem bug.  This is as good as the v12 runs from before.

Since this include and the one for mm_types.h both are build breakages
for ia64, I think you need to apply your ia64_cpumask and the following
(possibly as a single patch) first or in your patch 1.  Without that,
ia64 doing a git-bisect could hit a build failure.
