    The same day, Linus Torvalds replied:

    That's what my original patch was doing, but Mark M. Hoffman objected
    that it didn't cover the case where the user hits the reset button.

    Given that PEC is only rarely used, the slight performance impact isn't
    an issue, so I'm fine with both patches.
