That's it, yes. It needed a little more rework than that
(see ChangeLog) but that's the main thrust.

Sorry, no. When I sent out the patches a second time to Andrew (didn't
copy LKML since nothing really changed from the first time in July),
I did CC Martin in the hope that he might feel the urge to run up
some numbers (or at least let him be aware of that change lest he
misinterpret numbers), but I think he was busy with other stuff.
All I had on it was the 10% off lmbench fork numbers on my 2*HT*P4.

Sorry, I'm going to have to leave you to sort this out with someone else
(I think Nick has replied), I'm not familiar with it, and I'm falling
way behind with the things I need to attend to.

Yeah!
