[Qemu-devel] [PATCH uq/master] apic: Fix legacy vmstate loading for KVM

[Jan Kiszka]

From: Jan Kiszka <address@hidden>

Also in case of loading pre-vmstate machines, we also need to open-code
the reading of the timer expires value and instead call the post_load
callback to apply it (or not). This fixes loading of legacy states into
the KVM APIC.
