[Qemu-devel] [PATCH 3/3] apic: always update the in-kernel status after loading |

The LAPIC is loaded separately from the rest of the VCPU state. Thus,
when restoring the CPU the dummy post-reset state is passed to the
in-kernel APIC.
This can cause MSI injection to fail if attempted during the restore of
another device, because the LAPIC believes it's not enabled.
