Subject: [git pull] IOMMU updates for 3.2
Hi Linus,
The following changes since commit 899e3ee404961a90b828ad527573aaaac39f0ab1:
Linux 3.1-rc10 (2011-10-17 21:06:23 -0700)
are available in the git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git next
The most important changes I ask you to pull are:
* Move of the OMAP IOMMU driver to drivers/iommu for future
code consolidation with other IOMMU drivers (by Ohad)
* Generic IO page-fault reporting added to the IOMMU-API (by Ohad,
currently only supported by OMAP IOMMU, but others will follow soon)
* The iommu_ops are not global anymore but a property of the bus_type
now. This is indirectly required by the upcoming VFIO driver developed
by Alex Williamson for KVM. This change touches the Device driver core
and is acked by Greg. This change also allows more consolidation in
the per-device handling code across IOMMU drivers (by me)
* The dma-debugging code does not yell anymore on sub-range sync calls
(by Neil)
* Various other fixes
The top-commit-id of the next branch on my local machine is
1abb4ba596a91a839f82e0c9c837b777d574e83d
Please pull. Shortlog and diff-stat attached.
