kvm: x86: Save/restore KVM-specific CPU states
Save and restore all so far neglected KVM-specific CPU states. Handling the TSC stabilizes migration in KVM mode. The interrupt_bitmap and mp_state are currently unused, but will become relevant for in-kernel irqchip support. By including proper saving/restoring already, we avoid having to increment CPU_SAVE_VERSION later on once again. v2: - initialize mp_state runnable (for the boot CPU) Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
