[PATCH] timer-irq-driven soft-watchdog, cleanups

Browse source

Make the softlockup detector purely timer-interrupt driven, removing
softirq-context (timer) dependencies.  This means that if the softlockup
watchdog triggers, it has truly observed a longer than 10 seconds
scheduling delay of a SCHED_FIFO prio 99 task.

(the patch also turns off the softlockup detector during the initial bootup
phase and does small style fixes)
