Updated commit message for BRBE detection infrastructure patch

Added documentation for struct arm_pmu changes, updated commit message Changed the BRBE driver as per proposed BRBE related perf ABI changes (V5) Changed all SYS_BRBXXXN_EL1 register definition encodings per Marc Process new perf branch types via PERF_BR_EXTEND_ABIĬhanges in RFC Added branch_sample_priv() while consolidating other branch sample filter helpers Use cached perfmon_capable() while configuring BRBE branch record filtersĬhanges in Added CONFIG_PERF_EVENTS wrapper for all branch sample filter helpers Added new hw_perf_event.flags element ARMPMU_EVT_PRIV to cache perfmon_capable() Dropped branch sample filter helpers consolidation patch from this series Rob's concerns regarding the series structure, arm_pmu callbacks based framework Jame's concerns regarding using perf_event_paranoid along with perfmon_capable() Jame's concerns regarding permission inadequacy related to perfmon_capable() (V7) that was posted earlier, and a branch sample filter helper issues have been resolved This series applies on v6.0-rc4 after the BRBE related perf ABI changes series Relevant register definitions could be accessed here. Via a new arch feature called Branch Record Buffer Extension (BRBE).
