Merge tag 'intr-remapping-ops-for-ingo' of git://git.kernel.org/pub/scm/linux/kernel...

- This patchset introduces a generic ops-interface for
  accessing interrupt remapping hardware on x86. It factors
  out the VT-d specific code from io_apic.c and moves it to
  drivers/iommu. These changes will be used to add support for
  AMD interrupt remapping hardware.
