[V6 01/11] perf: Add PERF_SAMPLE_BRANCH_COND

From: Anshuman Khandual
Date: Wed May 21 2014 - 06:02:04 EST


This patch introduces new branch filter PERF_SAMPLE_BRANCH_COND which
will extend the existing perf ABI. Various architectures can provide
this functionality with either with HW filtering support (if present)
or with SW filtering of captured branch instructions.
