    That's the original 64% regression..

    And then with the patch set:

    > \ | \
    > 71190 180% 199232 ± 4% will-it-scale.per_thread_ops

    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.
