The bulk of the motivation for this and description of crypto vulnerabilities is in the first patch of this series. The following three patches then fix up entropy accounting for the new model. The last patch fixes a minor code safety issue. This v3 fixes comments and commit message wording, simplifies a bit of code in a cmpxchg loop, and adjusts semantics around the poll write wakeup threshold. Jason A.
