Adrian Hunter 246eba8e90 perf tools: Add support for PERF_RECORD_TEXT_POKE 
Add processing for PERF_RECORD_TEXT_POKE events. When a text poke event
is processed, then the kernel dso data cache is updated with the poked
bytes.

Arnaldo Carvalho de Melo 40c7d2460e perf tools: Move routines that probe for perf API features to separate file 
Trying to disentangle this a bit further, unfortunately it uses
parse_events(), its interesting to have it separated anyway, so do it.
