Subject: [PATCH v2 0/3] KVM: x86: dump_vmcs: don't assume GUEST_IA32_EFER, show MSR autoloads/autosaves

v2:
- Don't use vcpu->arch.efer when GUEST_IA32_EFER is not available (Paolo).
- Show EFER and PAT seperately, as appropriate.
- Dump the MSR autoload/autosave lists (Paolo).

David Edmondson (3):
  KVM: x86: dump_vmcs should not assume GUEST_IA32_EFER is valid
  KVM: x86: dump_vmcs should not conflate EFER and PAT presence in VMCS
  KVM: x86: dump_vmcs should include the autoload/autostore MSR lists
