Impact: cleanup, robustization 1) guard ack_bad_irq with printk_ratelimit since there is no guarantee we will not be flooded one day 2) use pr_emerg() helper Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> LKML-Reference: <20090412165058.277579847@openvz.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
