[PATCH] reduce NMI watchdog call frequency with local APIC.
From: Mikael Pettersson <mikpe@csd.uu.se>
The real problem is that SMP with nmi_watchdog=2 initialises the lapic NMI
watchdog but doesn't check it and therefore doesn't reduce nmi_hz. This is
an SMP bug.
The patch changes smpboot.c to do a check_nmi_watchdog() at the appropriate
place, which fixes the high NMI frequency problem w/o changing anything
else. I've verified that it solves the problem on my MP-capable UP box.
