The --fields option is to allow user setup output field in any order. It can recieve any sort keys and following (hpp) fields:
overhead, overhead_sys, overhead_us, sample and period
If guest profiling is enabled, overhead_guest_{sys,us} will be available too.
More more information, please see previous patch "perf report: Add -F option to specify output fields"
