Subject: [PATCHv4 0/9] perf tool: parser generator for events parsing

hi,
Here's new version of event parsing patchset. To summarize:
 - adding event parser bison/flex generator
 - the event syntax stays as it was
 - adding event format sysfs group attribute
   for pmu device
 - adding new syntax to specify raw events based
   on the sysfs pmu's format attribute
   eg. "cpu/config=1,config1=2,config2=3/u"

There are helping patches 1-4, which I did not want to
mangle with the actual change. Patches 5-9 implement
the feature itself.

v4 changes:
 - 5/9 changed sysfs pmu format definitions to the group attribute,
       each line (in previous patch) is now represented by single
       sysfs attribute under format group
 - 6/9 fix raw events so the number is always considered to be hex number
 - 8/9 move config[12] definitions to be processed by the parser

Attached patches:
 1/9 perf, tool: Make perf_evlist__splice_list_tail global
 2/9 perf, tool: Remove unused functions from debugfs object
 3/9 perf, tool: Add sysfs mountpoint interface
 4/9 perf, tool: Add bitmap_or function into bitmap object
 5/9 perf: Adding sysfs group format attribute for pmu device
 6/9 perf, tool: Add parser generator for events parsing
 7/9 perf, tool: Add config options support for event parsing
 8/9 perf, tool: Add perf pmu object to access pmu format definition
 9/9 perf, tool: Add support to specify pmu style event


thanks,
jirka
