Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"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"
