Bug description:
Could we have basic profiling & tracing options enabled in Linaro
kernel? I'd suggest:
CONFIG_HIGH_RES_TIMERS=y (for using hrtimers as a sampling clock)
CONFIG_LOCAL_TIMERS=y (for A9 targets, otherwise hrtimers don't work)
CONFIG_PROFILING=y
CONFIG_PERF_EVENTS=y
CONFIG_HW_PERF_EVENTS=y
CONFIG_FTRACE=y
CONFIG_TRACING=y and/or CONFIG_GENERIC_TRACER=y (enabled by any tracer, eg.
when ENABLE_DEFAULT_TRACERS=y)
