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
