From: Namhyung Kim <namhyung@xxxxxxxxxx> [ Upstream commit db4b284029099224f387d75198e5995df1cb8aef ] andle 'p_stage_cyc' (for pipeline stage cycles) sort key with the same rationale as for the 'weight' and 'local_weight', see the fix in this series for a full explanation. Not sure it also needs the local and global variants. But I couldn't test it actually because I don't have the machine.
