Hi Linus,

Please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/ohad/hwspinlock.git for-linus

To receive hwspinlock updates for 3.2.

The only noticeable change is a new hwspinlock driver for
ST-Ericsson's u8500 platform by Mathieu; the rest of the changes are
either cleanups or trivial fixes (one of the fixes also trivially
changes a mach-omap2 file, and is Acked by Tony).

All of the patches have been tested in linux-next and currently there
are no merge conflicts, though I expect one to happen with the arm-sco
tree, as reported (and fixed) by Stephen earlier this month (see

I've flagged one of the fixes as stable material (the one from Juan).
Normally I would only send you stable-worthy patches during the rc
cycle and not wait until the merge window, but since the hwspinlock
tree and its upstream path have only materialized quite late in the
cycle (see https://lkml.org/lkml/2011/9/21/249), I've decided this
time to wait for the merge window.

Hope it's ok; please tell me if there are any issues.

I already have it in mmc-next, but it's fine to send it through your
branch instead:
