Merge branch 'turbostat' of https://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux into pm-tools
Pull turbostat changes for v4.3 from Len Brown. * 'turbostat' of https://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: tools/power turbostat: fix typo on DRAM column in Joules-mode tools/power turbostat: fix parameter passing for forked command tools/power turbostat: dump CONFIG_TDP tools/power turbostat: cpu0 is no longer hard-coded, so update output tools/power turbostat: update turbostat(8)
