[PATCH v2 0/2] KVM: x86: guest interface for SEV live migration

[Paolo Bonzini <pbonzini@redhat.com>]

This is a reviewed version of the guest interface (hypercall+MSR)
for SEV live migration.  The differences lie mostly in the API
for userspace.  In particular:

- the CPUID feature is not exposed in KVM_GET_SUPPORTED_CPUID

- the hypercall must be enabled manually with KVM_ENABLE_CAP

- the MSR has sensible behavior if not filtered (reads as zero,
  writes must leave undefined bits as zero or they #GP)

v1->v2: reviewed KVM_CAP_EXIT_HYPERCALL semantics,
	split CPUID bits so that the migration control MSR
	can be used for TDX
