[PATCH v2 0/5] x86/iommu: make CX16 mandatory for IOMMU

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following series is the original CX16 series sent by Teddy, with the
CX16 checks split into a separate patch, plus one extra patch to switch
AMD-Vi to use CMPXCHG16B when updating Interrupt Remapping Entries.

Note that last patch to use CMPXCHG16B fixes a real bug with AMD
hardware.

Thanks, Roger.

Roger Pau Monne (1):
  iommu/amd: atomically update IRTE

Teddy Astie (4):
  x86/iommu: check for CMPXCHG16B when enabling IOMMU
  iommu/vtd: remove non-CX16 logic from interrupt remapping
  x86/iommu: remove non-CX16 logic from DMA remapping
  iommu/vtd: cleanup MAP_SINGLE_DEVICE and related code
