This is the second revision of a patchset allowing multiple sources to select the same sink for a session which is a prerequisite for the support of CoreSight CPU-wide trace scenarios. The sink ID is communicated to the kernel by way of the event's configuration attribute (event::attr:config2). The ID itself is an hash of the sink's name, something that is readily available and doesn't require the addition of a new information field in the coresight_device structure. With this set the mechanic to communicate sink selection to the kernel via sysfs is no longer needed and removed. Applies cleanly and tested on 5.0-rc3. Thanks, Mathieu Changes for V2: * Addressed memory leak in etm_perf_add_symlink_sink() * Keep track of device attribute for future removal. * Added PMU attribure for config2. * Fixed email address signature.
