While "Fast CRC computation for generic polynomials using PCLMULQDQ instruction" is a well-known paper in the realm of specialized CRC and compression algorithms for the x86 architecture that has seen widespread implementation, not everyone is aware of it, and it's nevertheless a good practice to cite the sources ideas and knowledge come from.
Let's add a comment to the
pclmulqdq
module citing the whitepaper, including a link to a mirror hosting its PDF, for easy access by prospective contributors and other interested parties.
