Adrian Hunter 8f5b7e3f41 perf intel-pt: Fix occasional decoding errors when tracing system-wide ... commit 3d918fb13abdbeca7947578f5d7e426eafad7f5e upstream. In order to successfully decode Intel PT traces, context switch events are needed from the moment the trace starts. Currently that is ensured by using the 'immediate' flag which enables the switch event when it is opened. However, since commit 86c2786994 ("perf intel-pt: Add support for PERF_RECORD_SWITCH") that might not always happen. When tracing system-wide the context switch event is added to the tracking event which was not set as 'immediate'. Change that so it is.
