  vfio: always select ANON_INODES (2014-03-27 11:58:58 -0600)

----------------------------------------------------------------
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).

----------------------------------------------------------------

      vfio/iommu_type1: Multi-IOMMU domain support
