[PATCH 38/44] tools/power turbostat: move --Package and --processor into the --cpu option

[Len Brown]

From: Len Brown <len.brown@xxxxxxxxx>

--Package is now "--cpu package",
which will display just the 1st CPU in each package

--processor is not "--cpu core"
which will display just the 1st CPU in each core

-\fB--cpu cpu-set\fP limit output to system summary plus the specified cpu-set.  cpu-set is a comma delimited list of cpu ranges. cpu ranges can be individual cpu numbers or start and end numbers, separated by ".." or '-'.  eg. 1,2,8,14..17,21-44
+\fB--cpu cpu-set\fP limit output to system summary plus the specified cpu-set.  If cpu-set is the string "core", then the system summary plus the first CPU in each core are printed -- eg. subsequent HT siblings are not printed.  Or if cpu-set is the string "package", then the system summary plus the first CPU in each package is printed.  Otherwise, the system summary plus the specified set of CPUs are printed.  The cpu-set is ordered from low to high, comma delimited with ".." and "-" permitted to denote a range. eg. 1,2,8,14..17,21-44
