For example, a POWER6 system in\nsingle-threaded mode (i.e. only running 1 hardware thread per\ncore) will have only even-numbered cpus online.\n\nThis fixes the problem by reading the /sys/devices/system/cpu/online\nfile to find out which cpus are online. The code that does that is in\ntools/perf/util/cpumap.[ch], and consists of a read_cpu_map()\nfunction that sets up a cpumap[] array and returns the number of\nonline cpus.
