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

Thanks.
CC Oleksii. Patch 5 is a real bugfix that needs backporting, and the
prior patches have been in an almost-ready state for more than a release
now.
I've split the checks into a pre-patch, and did a bit more cleanup of
code that was no longer needed (pre/post interrupt mask before IRTE
update), but overall the code is the same plus the extra fix.
Thanks, Roger.
