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.
