Merge tag 'vfio-v3.15-rc1' of git://github.com/awilliam/linux-vfio

Pull VFIO updates from Alex Williamson:
 "VFIO updates for v3.15 include:

   - Allow the vfio-type1 IOMMU to support multiple domains within a
     container
   - Plumb path to query whether all domains are cache-coherent
   - Wire query into kvm-vfio device to avoid KVM x86 WBINVD emulation
   - Always select CONFIG_ANON_INODES, vfio depends on it (Arnd)

  The first patch also makes the vfio-type1 IOMMU driver completely
  independent of the bus_type of the devices it's handling, which
  enables it to be used for both vfio-pci and a future vfio-platform
  (and hopefully combinations involving both simultaneously)"

* tag 'vfio-v3.15-rc1' of git://github.com/awilliam/linux-vfio:
  vfio: always select ANON_INODES
  kvm/vfio: Support for DMA coherent IOMMUs
  vfio: Add external user check extension interface
  vfio/type1: Add extension to test DMA cache coherence of IOMMU
  vfio/iommu_type1: Multi-IOMMU domain support
