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
