Merge branch 'turbostat' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux

Pull turbostat utility changes for 4.18-rc2 from Len Brown.

"This includes two regression fixes, plus a couple more random, but
 worthy, patches."

* 'turbostat' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux:
  tools/power turbostat: version 18.06.20
  tools/power turbostat: add the missing command line switches
  tools/power turbostat: add single character tokens to help
  tools/power turbostat: alphabetize the help output
  tools/power turbostat: fix segfault on 'no node' machines
  tools/power turbostat: add optional APIC X2APIC columns
  tools/power turbostat: decode cpuid.1.HT
  tools/power turbostat: fix show/hide issues resulting from mis-merge
