Michal Schmidt 9938406ab6 [PATCH] Make touch_nmi_watchdog imply touch_softlockup_watchdog on all archs
touch_nmi_watchdog() calls touch_softlockup_watchdog() on both
architectures that implement it (i386 and x86_64).  On other architectures
it does nothing at all.  touch_nmi_watchdog() should imply
touch_softlockup_watchdog() on all architectures.  Suggested by Andi Kleen.
