sry for delay, I was out last week

I put something together and pushed it in here:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/annotate_percent

there's the 'p' key to switch between local and global period
I haven't added any command line option for stdio yet

I'll have more testing and post later but any feedback
now would be great

thanks,
