The linux kernel also uses it when it's availabe, see e.g.
http://tomoyo.sourceforge.jp/cgi-bin/lxr/source/arch/x86/crypto/crc32c-intel.c
If you guys are interested I have a Core i7 here, could run a little
benchmark.

This sounds familiar. If you search back in the archives around 2004
or so I think you'll find a similar discussion when we replaced the
crc32 implementation with what we have now. We put a fair amount of
effort into searching for faster implementations so if you've found
one 3x faster I'm pretty
