    Subject[PATCH V3 23/26] perf tools: making function set_max_cpu_num() non static
    Date
    For memory allocation purposes, code located in other places
    then util/cpumap.c may want to know how many CPUs the system has.

    This patch is making function set_max_cpu_num() available to
    other parts of the perf tool so that global variable
    @max_cpu_num gets the right value when referenced by cpu__max_cpu().
