[PATCH 1/2] cpufreq, powernow: enable/disable core performance boost for all cpus in policy
Currently, enable/disable turbo mode on AMD is broken:
$ xenpm enable-turbo-mode 0 <-- works and proper CPU MSR bit is set
$ xenpm enable-turbo-mode 1 <-- silently broken, MSR bit not set
Since ->turbo is per policy, when user requests to enable/disable
turbo mode, we need to set the bit in all of the ->cpus that this
policy affects.

[PATCH] xenpm: make argument parsing and error handling more consistent
...stderr, and the tool should now (hopefully) produce an exit code of
zero only in the (partial) success case (there may still be a small
number of questionable cases).
