Suzuki K Poulose f9d81a657b coresight: perf: Allow tracing on hotplugged CPUs ... At the moment, if there is no CPU specified for a given event, we use cpu_online_mask and try to build path for each of the CPUs in the mask. This could prevent any CPU that is turned online later to be used for the tracing. This patch changes to use the cpu_present_mask and tries to build path for as much CPUs as possible ignoring the failures in building path for some of the CPUs. If ever we try to trace on those CPUs, we fail the operation. Based on a patch from Mathieu Poirier.
