v1:
  - fix typos and some phrases (Laszlo)
  - add unplug check (Laszlo)
  - redo AML scan logic to avoid race when adding multiple CPUs

CPU hotplug with Secure Boot was not really supported and firmware wasn't aware
of hotplugged CPUs (which might lead to guest crashes). During 4.2 we introduced
locked SMI handler RAM arrea to make sure that guest OS wasn't able to inject
its own SMI handler and OVMF added initial CPU hotplug support.

This series is QEMU part of that support which lets QMVF tell QEMU that
CPU hotplug with SMI broadcast enabled is supported so that QEMU would be able
to prevent hotplug in case it's not supported and trigger SMI on hotplug when
it's necessary. 


Igor Mammedov (6):
  x86: lpc9: let firmware negotiate 'CPU hotplug with SMI' features
  x86: cphp: prevent guest crash on CPU hotplug when broadcast SMI is in
    use
  x86: cpuhp: refuse cpu hot-unplug request earlier if not supported
  tests: acpi: mark to be changed tables in
    bios-tables-test-allowed-diff
  x68: acpi: trigger SMI before scanning for hotplugged CPUs
  tests: acpi: update acpi blobs with new AML
