Mark the coretemp(4) sysctls as MPSAFE, ensuring that Giant won't be held unnecessarily by a user thread waiting to run on a specific CPU after calling sched_bind().

#PROCHOT assertion is sticky after reading the MSR (accordingly with

Xeon 5500/5600 series: - Utilize IA32_TEMPERATURE_TARGET, a.k.a. Tj(target) in place of Tj(max) when a sane value is available, as documented in Intel whitepaper "CPU Monitoring With DTS/PECI"; (By sane value we mean 70C - 100C for now); - Print the probe results when booting verbose; - Replace cpu_mask with cpu_stepping; - Use CPUID_* macros instead of rolling our own.
