          The overhead should be minimal.  A periodic hrtimer runs to
          generate interrupts and kick the watchdog task every 4 seconds.
          An NMI is generated every 10 seconds or so to check for hardlockups.
+         If NMIs are not available on the platform, every 12 seconds the
+         hrtimer interrupt on one cpu will be used to check for hardlockups
+         on the next cpu.
 
          The frequency of hrtimer and NMI events and the soft and hard lockup
          thresholds can be controlled through the sysctl watchdog_thresh.
