[PATCH] powerpc: remove useless call to touch_softlockup_watchdog
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.
