[git,pull] Please pull powerpc.git merge branch

Hi Linus !

Here's the powerpc bunch for this merge window. Small this time, looks
like Kumar was too busy with holidays to send me anything from freescale
this time around.

There's some rework & cleanup of our nvram code, some support for the
POWER7+ processors, various iommu cleanups, etc... in terms of features,
we can note the support for some of IBM System P energy management and
VPHN feature which improves NUMA topology informations under our
hypervisor.

The following changes since commit 5b2eef966cb2ae307aa4ef1767f7307774bc96ca:

  Merge branch 'drm-core-next' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6 (2011-01-10 17:11:39 -0800)
