Jörg, please pull into your x86/vt-d branch from

	git://git.infradead.org/iommu-2.6

This contains the two patch sets I've posted in the last week; first the
set which fixes the use-after-free issues with IOTLB flushes, adds some
missing IOTLB flushes and generally improves unmap performance. And then
the support for DMA mapping of ACPI devices.

This contains a couple of fixes triggered by Fengguang's build-test
robots; one of which was posted as [PATCH 34/33] a few hours ago, and
the other of which just moves the 'segment' member of struct intel_iommu
outside the #ifdef CONFIG_INTEL_IOMMU since it's accessed from dmar.c
without that config option set. I've merged both of those fixes back
into the original offending patch, rather than putting them on top.
