It turns out that we can't stop the watchdog from
triggering here.  If we touch the timer (which just uses the current jiffie
value) before we enable interrupts, it does nothing because jiffies
are not mass-updated until after we enable interrupts.  If we touch the
timer after we enable interrupts, its too late because the softlockup
watchdog will already have triggered.  The touch_softlockup_watchdog
call removed below does nothing.
