Subject: [git pull] IOMMU Updates for v3.8

(Somehow my first mail was lost, at least I can't find it on LKML or the
 IOMMU list, so here it is again)

Hi Linus,

The following changes since commit 29594404d7fe73cd80eaa4ee8c43dcc53970c60e:

  Linux 3.7 (2012-12-10 19:30:57 -0800)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git tags/iommu-updates-v3.8

for you to fetch changes up to 9c6ecf6a3ade2dc4b03a239af68058b22897af41:

  Merge branches 'iommu/fixes', 'dma-debug', 'x86/amd', 'x86/vt-d', 'arm/tegra' and 'arm/omap' into next (2012-12-16 12:24:09 +0100)

IOMMU Updates for Linux v3.8

A few new features this merge-window. The most important one is
probably, that dma-debug now warns if a dma-handle is not checked with
dma_mapping_error by the device driver. This requires minor changes to
some architectures which make use of dma-debug. Most of these changes
have the respective Acks by the Arch-Maintainers.
Besides that there are updates to the AMD IOMMU driver for refactor the
IOMMU-Groups support and to make sure it does not trigger a hardware
erratum.
The OMAP changes (for which I pulled in a branch from Tony Lindgren's
tree) have a conflict in linux-next with the arm-soc tree. The conflict
is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in
the arm-soc tree. It is safe to delete the file too so solve the
conflict. Similar changes are done in the arm-soc tree in the common
clock framework migration. A missing hunk from the patch in the IOMMU
tree will be submitted as a seperate patch when the merge-window is
closed.
