From: Eric Biggers <ebiggers@xxxxxxxxxx> Remove the vmac64 template, as it has no known users. It also continues to have longstanding bugs such as alignment violations (see https://lore.kernel.org/r/20241226134847.6690-1-evepolonium@xxxxxxxxx/).

No in-tree user has appeared since then, other than potentially the usual components that allow specifying arbitrary hash algorithms by name, namely AF_ALG and dm-integrity. However there are no indications that VMAC is being used with these components. Debian Code Search and web searches for "vmac64" (the actual algorithm name) do not return any results other than the kernel itself, suggesting that it does not appear in any other code or documentation. Explicitly grepping the source code of the usual suspects (libell, iwd, cryptsetup) finds no matches either.
AFAIK it was never used for dm-integrity / cryptsetup and I am not even able to make it work for test now (isn't the vmac64 alg module init even broken?). Just remove it... Thanks, Milan
