The function qemu_notify_event is defined by a header that we don't include in the PPC KVM code. Include it to get the code building again. target-ppc/kvm_ppc.c: In function 'kvmppc_timer_hack': target-ppc/kvm_ppc.c:26:5: error: implicit declaration of function 'qemu_notify_event' [-Werror=implicit-function-declaration] target-ppc/kvm_ppc.c:26:5: error: nested extern declaration of 'qemu_notify_event' [-Werror=nested-externs] Signed-off-by: Alexander Graf <agraf@suse.de>
