From: "Srivatsa S. Bhat (VMware)" <srivatsa@xxxxxxxxxxxxx> The comment that says mwait_play_dead() returns only on failure is a bit misleading because mwait_play_dead() could actually return for valid reasons (such as mwait not being supported by the platform) that do not indicate a failure of the CPU offline operation. So, remove the comment. Suggested-by: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Signed-off-by: Srivatsa S.
