Pull x86 TDX updates from Dave Hansen:
"Avoid direct HLT instruction execution in TDX guests.
TDX guests aren't expected to use the HLT instruction directly. It
causes a virtualization exception (#VE). While the #VE _can_ be
handled, the current handling is slow and buggy and the easiest thing
is just to avoid HLT in the first place. Plus, the kernel already has
paravirt infrastructure that makes it relatively painless.
Make TDX guests require paravirt and add some TDX-specific paravirt
handlers which avoid HLT in the normal halt routines. Also add a
warning in case another HLT sneaks in.
There was a report that this leads to a "major performance
improvement" on specjbb2015, probably because of the extra #VE
overhead or missed wakeups from the buggy HLT handling"

emulating a vIOMMU. ARM SMMUv3 is the first driver to use this
mechanism. Like the existing fault events the data is delivered
through a simple FD returning event records on read().
- PASID support in VFIO.

device to tag all PCI DMA operations with an ID. The IOMMU will
