Subject: [GIT PULL] parisc fixes for 3.4-rc1
Date: Fri, 31 Aug 2012 09:01:11 -0700	[thread overview]
Message-ID: <1346428871.3512.21.camel@dabdike> (raw)

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:
