Modified Files: src/sys/arch/x86/include: cpu_counter.h src/sys/arch/x86/x86: cpu.c tsc.c Log Message: Some CPU have cpu counter (CPUID_TSC is there) but don't handle the rdmsr instruction (CPUID_MSR is not there). Introduce a cpu_counter_serializing() function to remplace rdmsr(MSR_TSC) calls, which does a rdmsr(MSR_TSC) if available and cpu_counter() otherwise. This makes the cpu counter useable on vortex86 CPUs.
