Hi Arnaldo,
The following changes since commit 89fee59b504f86925894fcc9ba79d5c933842f93:
perf tools: handle spaces in file names obtained from /proc/pid/maps (2016-02-05 09:39:56 -0300)

perf tools: Don't warn about out of order event if write_backward is used (2016-02-05 13:44:29 +0000)
---------------------------------------------------------------- perf improvements:
- Code clean: based on Arnaldo's suggestion.
- Remove '-e evt=cycles' symtax. Enforce existing 'cycles/name=evt/' syntax.
- Forbid improper config terms passing to 'perf stat'. i.e. 'perf stat -e cycles/no-inherit/ ...'
