softlockup: fix false positives on CONFIG_NOHZ
David Miller reported soft lockup false-positives that trigger on NOHZ due to CPUs idling for more than 10 seconds. The solution is touch the softlockup watchdog when we return from idle. (by definition we are not 'locked up' when we were idle) http://bugzilla.kernel.org/show_bug.cgi?id=9409 Reported-by: David Miller <davem@davemloft.net> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
