[PATCH 0/3] Introduce MSI hardware mapping for VFIO

[Pavel Fedin <p.fedin@samsung.com>]

On some architectures (e.g. ARM64) if the device is behind an IOMMU, and
is being mapped by VFIO, it is necessary to also add mappings for MSI
translation register for interrupts to work. This series implements the
necessary API to do this, and makes use of this API for GICv3 ITS on
ARM64.

Pavel Fedin (3):
  vfio: Introduce map and unmap operations
  gicv3, its: Introduce VFIO map and unmap operations
  vfio: Introduce generic MSI mapping operations
