Very nice speedup. On

Branch History Rolling Buffer (BHRB) is a new PMU feaure in IBM
POWER8 processor which records the branch instructions inside the execution
pipeline. This patchset enables the basic functionality of the feature through
generic perf branch stack sampling framework.
Sample output
---
This patch adds the basic assembly code to read BHRB buffer. BHRB entries
are valid only after a PMU interrupt has happened (when MMCR0[PMAO]=1)
and BHRB has been freezed. BHRB read should not be attempted when it is
still enabled (MMCR0[PMAE]=1) and getting updated, as this can produce
non-determi
Provides basic enablement for perf branch stack sampling framework on
POWER8 processor based platforms. Adds new BHRB related elements into
cpu_hw_event structure to represent current BHRB config, BHRB filter
configuration, manage context and to hold output BHRB buffer during
PMU interrupt before p
This patch adds new POWER8 instruction encoding for reading
the BHRB buffer entries and also clearing it. Encoding for
"clrbhrb" instruction is straight forward. But "mfbhrbe"
encoding involves reading a certain index of BHRB buffer
into a particular GPR register.

This patch adds couple of generic functions to power_pmu structure
which would configure the BHRB and it's filters. It also adds
representation of the number of BHRB entries present on the PMU.
A new PMU flag PPMU_BHRB would indicate presence of BHRB feature.

This patch populates BHRB specific data for power_pmu structure. It
also implements POWER8 specific BHRB filter and configuration functions.
