Merge git://git.kernel.org/pub/scm/linux/kernel/git/brodo/cpupowerutils
* git://git.kernel.org/pub/scm/linux/kernel/git/brodo/cpupowerutils:
cpupower: use man(1) when calling "cpupower help subcommand"
cpupower: make NLS truly optional
cpupower: fix Makefile typo
cpupower: Make monitor command -c/--cpu aware
cpupower: Better detect offlined CPUs
cpupower: Do not show an empty Idle_Stats monitor if no idle driver is available
cpupower: mperf monitor - Use TSC to calculate max frequency if possible
cpupower: avoid using symlinks
