From: "Srivatsa S. Bhat (VMware)" <sriva...@csail.mit.edu>
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.
