Right, there's a good solid reason for all the work on the scheduler.  I
definitely think we ought to be following the same approach on both
ARMv7 and ARMv8 to avoid confusion between people based on the platform
they're working on.

If you're saying that the current ARMv7 code is always worse than doing
nothing then clearly we ought to be removing that code from ARMv7 rather
than hurting performance.  I'd been under the impression that what we
had there was not ideal but better than nothing in mainline rather than
actively harmful.
