This is a set of two bug fixes.  One is the ATOMIC problem which is now
causing a compile failure in certain situations.  The other is
mishandling of PER_LINUX32 which may also cause user visible effects.

The patches are here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/parisc-2.6.git parisc-fixes

The short changelog is:

Jiri Kosina (1):
      fix personality flag check in copy_thread()

Mel Gorman (1):
      Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts

And the diffstat:
