The --fields option is to allow user setup output field in any order.
It can receive 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"
