v2:
- Don't use vcpu->arch.efer when GUEST_IA32_EFER is not available (Paolo).
- Dump the MSR autoload/autosave lists (Paolo).

v3:
- Rebase to master.
- Check only the load controls (Sean).
- Always show the PTPRs from the VMCS if they exist (Jim/Sean).
- Dig EFER out of the MSR autoload list if it's there (Paulo).
- Calculate and show the effective EFER if it is not coming from
  either the VMCS or the MSR autoload list (Sean).

v4:
- Ensure that each changeset builds with just the previous set.

David Edmondson (5):
  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 consider only the load controls of EFER/PAT
  KVM: x86: dump_vmcs should show the effective EFER
  KVM: x86: dump_vmcs should include the autoload/autostore MSR lists
