x86, apic: Enable lapic nmi watchdog on AMD Family 11h
The x86 lapic nmi watchdog does not recognize AMD Family 11h, resulting in: NMI watchdog: CPU not supported As far as I can see from available documentation (the BKDM), family 11h looks identical to family 10h as far as the PMU is concerned. Extending the check to accept family 11h results in: Testing NMI watchdog ... OK. I've been running with this change on a Turion X2 Ultra ZM-82 laptop for a couple of weeks now without problems.
