Pull KVM updates from Paolo Bonzini:
"ARM:
- More progress on the protected VM front, now with the full fixed
feature set as well as the limitation of some hypercalls after
initialisation.
- Cleanup of the RAZ/WI sysreg handling, which was pointlessly
complicated
- Fixes for the vgic placement in the IPA space, together with a
bunch of selftests
- More memcg accounting of the memory allocated on behalf of a guest
- Timer and vgic selftests
- Workarounds for the Apple M1 broken vgic implementation
- KConfig cleanups
- New kvmarm.mode=none option, for those who really dislike us
RISC-V:
- New KVM port.
x86:
- New API to control TSC offset from userspace
- TSC scaling for nested hypervisors on SVM
- Switch masterclock protection from raw_spin_lock to seqcount
- Clean up function prototypes in the page fault code and avoid
repeated memslot lookups
- Convey the exit reason to userspace on emulation failure
- Configure time between NX page recovery iterations
- Expose Predictive Store Forwarding Disable CPUID leaf
- Allocate page tracking data structures lazily (if the i915 KVM-GT
functionality is not compiled in)
- Cleanups, fixes and optimizations for the shadow MMU code
s390:
- SIGP Fixes
- initial preparations for lazy destroy of secure VMs
- storage key improvements/fixes
- Log the guest CPNC
Starting from this release, KVM-PPC patches will come from Michael
Ellerman's PPC tree"
