Merge tag 'parisc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/parisc-2.6
Pull PARISC fixes from James Bottomley:
"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.
Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
