[GIT PULL] VT-d fixes and ACPI device mapping support for 3.15

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.

Again, please. A few minor fixes...

Dan Carpenter (1):
      iommu/vt-d: returning free pointer in get_domain_for_dev()

David Woodhouse (2):
      iommu/vt-d: Only call dmar_acpi_dev_scope_init() if DRHD units present
      iommu/vt-d: Fix error handling in ANDD processing
