Modified files:
sys/arch/amd64/amd64: pctr.c
sys/arch/i386/i386: pctr.c
Log message:
Use cpuid function 0xa to determine presence of general purpose
architectural performance counters, instead of cpu family/model values.
Fixes a panic seen on some hypervisors when pctr(1) is used when the
hypervisor masks out the counters.
Reported by Hiltjo Posthuma, thanks.
