The original patch that went into your mm tree was replaced by a cleaner one
over time but the review process went on and on and I had to spend more time
with my day job. Eventually I just couldn't figure out how to get everyone
any happier. I was really reluctant to give up performance on the Intel
platform
but we were mostly arguing about 2-3% give or take.

It seems that the folks that wanted the same algorithm for crc32c may have
figured out how to reach a compromise.
