[PATCH 0/3] crypto: Remove arch-optimized des and des3_ede code

[Eric Biggers <ebiggers@kernel.org>]

DES and 3DES are cryptographically obsolete and insecure by modern
standards.  Continuing to maintain highly specific, complex assembly and
glue code for them, especially when the code isn't testable in QEMU
(s390 and sparc), is unnecessary and risky.

Thus, this series removes the architecture-optimized DES and 3DES code
for the three architectures that had it: s390, sparc, and x86.

This series is targeting cryptodev/master.

Eric Biggers (3):
  crypto: s390 - Remove des and des3_ede code
  crypto: sparc - Remove des and des3_ede code
  crypto: x86 - Remove des and des3_ede code
