func CPUInfo

func CPUInfo() ([]CPUInfoStat, error)

CPUInfo on linux will return 1 item per physical thread.

CPUs have three levels of counting: sockets, cores, threads. Cores with HyperThreading count as having 2 threads per core. Sockets often come with many physical CPU cores. For example a single socket board with two cores each with HT will return 4 CPUInfoStat structs on Linux and the "Cores" field set to 1.
