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:

This is a set of three bug fixes for minor build breakages that got
introduced just before 3.4-rc1 was released.
The patches are here:

The short changelog is:
James Bottomley (3):
fix code to find libgcc
fix compile break in use of lib/strncopy_from_user.c
fix missing TAINT_WARN problem

3.4-rc1 or 3.5-rc1? I ask as if this is 3.4-rc1, these should go to the
stable tree, right?

Sorry, mislabel ... it's 3.5-rc1 ... they all fix breaks that were
introduced within the last week, so no need for a stable backport.
