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)
