  Merge tag 'kvm-x86-selftests-6.6-fixes' of https://github.com/kvm-x86/linux into HEAD (2023-10-15 08:25:18 -0400)

----------------------------------------------------------------
ARM:

- Fix the handling of the phycal timer offset when FEAT_ECV
  and CNTPOFF_EL2 are implemented.

- Restore the functionnality of Permission Indirection that
  was broken by the Fine Grained Trapping rework

- Cleanup some PMU event sharing code

MIPS:

- Fix W=1 build.

s390:

- One small fix for gisa to avoid stalls.

x86:

- Truncate writes to PMU counters to the counter's width to avoid spurious
  overflows when emulating counter events in software.

- Set the LVTPC entry mask bit when handling a PMI (to match Intel-defined
  architectural behavior).

- Treat KVM_REQ_PMI as a wake event instead of queueing host IRQ work to
  kick the guest out of emulated halt.

- Fix for loading XSAVE state from an old kernel into a new one.

- Fixes for AMD AVIC

selftests:

- Play nice with %llx when formatting guest printf and assert statements.

- Clean up stale test metadata.

- Zero-initialize structures in memslot perf test to workaround a suspected
  "may be used uninitialized" false positives from GCC.
