KVM: PPC: Book3S PR: Handle Facility interrupt and FSCR
POWER8 introduced a new interrupt type called "Facility unavailable interrupt" which contains its status message in a new register called FSCR. Handle these exits and try to emulate instructions for unhandled facilities. Follow-on patches enable KVM to expose specific facilities into the guest. Signed-off-by: Alexander Graf <agraf@suse.de>
