[PATCH V7 0/3] Adding support for address filters

[PATCH V7 0/3] Adding support for address filters

[Mathieu Poirier]

This patch set makes it possible to use the current filter
framework with address filters.  That way address filters for
HW tracers such as CoreSight and Intel PT can be communicated
to the kernel drivers.

In this revision precursor work is done to make function
perf_evsel__append_filter() generic, along with changes to
current customers.  From there the work on address filters is
introduced.

Thanks,
Mathieu

Changes for V7:
 - s/intelPT/Intel PT
 - Added Adrian's ack.

Changes for V6:
 - Split work in 3 (small) patches.
 - Adding tracepoint and address filter append() functions

Changes for V5:
 - Modified perf_evsel__append_filter() to take a string format
   rather than an operation.

Changes for V4:
 - Added support for address filters over more than one
   nibble.
 - Removed Jiri's ack, this version is too different from
   what was reviewed.

Changes for V3:
 - Added Jiri's ack.
 - Rebased to v4.8-rc5.

Changes for V2:
 - Rebased to v4.8-rc4.
 - Revisited error path.

[PATCH V7 2/3] perf tools: new tracepoint specific function

[Mathieu Poirier]

Making function perf_evsel__append_filter() static and
introducing a new tracepoint specific function to append
filters.  That way we eliminate redundant code and avoid
formatting mistake.

perf tools: Make perf_evsel__append_filter() generic

By making function perf_evsel__append_filter() take a format rather than
an operator it is possible to reuse the code for other purposes (ex.
Intel PT and CoreSight) than tracepoints.

perf evsel: New tracepoint specific function

Making function perf_evsel__append_filter() static and introducing a new
tracepoint specific function to append filters.  That way we eliminate
redundant code and avoid formatting mistake.
