Merge git://git.infradead.org/iommu-2.6
* git://git.infradead.org/iommu-2.6:
Admit to maintaining VT-d, for my sins.
dmar: fix uninitialised 'ret' variable in dmar_parse_dev()
intel-iommu: use coherent_dma_mask in alloc_coherent
amd_iommu: fix nasty bug that caused ILLEGAL_DEVICE_TABLE_ENTRY errors
intel-iommu: IA64 support
dmar: remove the quirk which disables dma-remapping when intr-remapping enabled
dmar: Use queued invalidation interface for IOTLB and context invalidation
dmar: context cache and IOTLB invalidation using queued invalidation
dmar: use spin_lock_irqsave() in qi_submit_sync()
