powerpc/perf: Add new BHRB related generic functions, data and flags
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. Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
