Ok, those test robot reports are hard to read, but trying to distill it down:

That's the original 64% regression..
And then with the patch set:

looks like it's back up where it used to be.
So I guess we have numbers for the regression now. Thanks.
And that closes my biggest question for the new model, and with the new organization that gets ird of the arch-specific asm separately first and makes it a bit more legible that way, I guess I'll just Ack the whole series.
