Sorry for the repost so soon after version 7. Version 8 fixes a build
error spotted by kbuild, due to mixing object file name and module name.
Other than that derp, it's identical to version 7.
Version 7 incorporates suggestions from the mailing list on version 6.
We now use a union type to handle the poly1305_core_key, per suggestion.
And now the changes to the cryptogams code are nicely split out into its
own commit, with detail on the (limited) scope of the changes. I believe
this should address the last of issues brought up.
####
These are some improvements to the Poly1305 code that I think should be
fairly uncontroversial. The first part, the new C implementations, adds
cleaner code in two forms that can easily be compared and reviewed, and
also results in performance speedups. The second part, the new x86_64
implementation, replaces an slow unvetted implementation with an
extremely fast implementation that has received many eyeballs. Finally,
we fix up some dead code.
Jason A. Donenfeld (4):
crypto: poly1305 - add new 32 and 64-bit generic versions
crypto: x86_64/poly1305 - import unmodified cryptogams implementation
crypto: x86_64/poly1305 - wire up faster implementations for kernel
crypto: arm/arm64/mips/poly1305 - remove redundant non-reduction from
