Venkatesh Pallipadi 1676193937 [PATCH] x86-64: Handle 32 bit PerfMon Counter writes cleanly in x86_64 nmi_watchdog
P6 CPUs and Core/Core 2 CPUs which has 'architectural perf mon' feature,
only supports write of low 32 bits in Performance Monitoring Counters.
Bits 32..39 are sign extended based on bit 31 and bits 40..63 are reserved
and should be zero.

This patch:

Change x86_64 nmi handler to handle this case cleanly.
