This patch enables SW based post processing of BHRB captured branches
to be able to meet more user defined branch filtration criteria in perf
branch stack sampling framework. These changes increase the number of
branch filters and their valid combinations on any powerpc64 server
platform with BHRB
Adding documentation support for conditional branch filter.

POWER8 PMU based BHRB supports filtering for conditional branches.
This patch introduces new branch filter PERF_SAMPLE_BRANCH_COND which
will extend the existing perf ABI. Other architectures can provide
this functionality with either HW filtering support (if present) or
with SW filtering of

filtering of branch records in perf. This patch also converts and

This patch adds enumeration for all available SW branch filters

Powerpc kernel now supports SW based branch filters for book3s systems with some
specifc requirements while dealing with HW supported branch filters in order to
achieve overall OR semantics prevailing in perf branch stack sampling framework.

This patch simply changes the name of the variable from bhrb_filter to
bhrb_hw_filter in order to add one more variable which will track SW
