Subject: [PATCH v2 0/6] ATS capability support for Intel IOMMU

This patch series implements Address Translation Service support for
the Intel IOMMU. ATS makes the PCI Endpoint be able to request the
DMA address translation from the IOMMU and cache the translation in
the Endpoint, thus alleviate IOMMU pressure and improve the hardware
performance in the I/O virtualization environment.

Changelog: v1 -> v2
  added 'static' prefix to a local LIST_HEAD (Andrew Morton)


Yu Zhao (6):
  PCI: support the ATS capability
  VT-d: parse ATSR in DMA Remapping Reporting Structure
  VT-d: add queue invalidation fault status support
  VT-d: add device IOTLB invalidation support
  VT-d: cleanup iommu_flush_iotlb_psi and flush_unmaps
  VT-d: support the device IOTLB
