Subject: [GIT PULL] hwspinlock fixes for 3.2

Hi Linus,

Please pull:

  git://git.kernel.org/pub/scm/linux/kernel/git/ohad/hwspinlock.git fixes

To get two hwspinlock fixes from Axel.

There was a third, "module.h split merge"-related fix from Axel that I
dropped because I saw Paul picked it up in his pull request.

Thanks,
Ohad.
