[PATCH] i386 prepare nmi watchdog for dynticks
The NMI watchdog implementation assumes that the local APIC timer interrupt is
happening. This assumption is not longer true when high resolution timers and
dynamic ticks come into play, as they may switch off the local APIC timer
completely. Take the PIT/HPET interrupts into account too, to avoid false
positives.
