- perf/arm-cci: allow building as module - perf/arm-ccn: demote dev_warn() to dev_dbg() in event_init() - miscellaneous perf/arm cleanups * 'for-next/perf' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux: ARM: mcpm, perf/arm-cci: export mcpm_is_available drivers/bus: arm-cci: fix build warnings drivers/perf: Remove ARM_SPE_PMU explicit PERF_EVENTS dependency drivers/perf: arm-ccn: don't log to dmesg in event_init perf/arm-cci: Allow building as a module perf/arm-cci: Remove pointless PMU disabling perf/arm-cc*: Fix MODULE_LICENSE() tags arm_pmu: simplify arm_pmu::handle_irq perf/arm-cci: Remove unnecessary period adjustment perf: simplify getting .drvdata
