[Qemu-devel] [PATCH 19/35] kvm: x86: Prepare kvm_get_mp_state for in-kernel irqchip

[Marcelo Tosatti]

From: Jan Kiszka <address@hidden>

This code path will not yet be taken as we still lack in-kernel irqchip
support. But qemu-kvm can already make use of it and drop its own
mp_state access services.
