Merge branch 'pm-tools' 

These are turbostat utility updates for 4.18-rc2 including two fixes
for recent regressions and some minor extensions.

* pm-tools:
  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
