  KVM: x86: nSVM: disallow userspace setting of MSR_AMD64_TSC_RATIO to non default value when tsc scaling disabled (2022-02-24 13:04:47 -0500)

----------------------------------------------------------------
x86 host:

* Expose KVM_CAP_ENABLE_CAP since it is supported

* Disable KVM_HC_CLOCK_PAIRING in TSC catchup mode

* Ensure async page fault token is nonzero

* Fix lockdep false negative

* Fix FPU migration regression from the AMX changes

x86 guest:

* Don't use PV TLB/IPI/yield on uniprocessor guests

PPC:
* reserve capability id (topic branch for ppc/kvm)
