Subject: [PATCH 0/2] crypto: x86 - AES-CTR and AES-XCTR rewrite

This series adds new implementations of AES-CTR and AES-XCTR that are
optimized for modern x86_64 CPUs, and it removes the existing
implementations that are superseded or obsolete.

Changed in v2:
- Split the removal of the non-AVX implementation of AES-CTR into a
  separate patch, and removed the assembly code too.
- Made some minor tweaks to the new assembly file, including fixing a
  build error when aesni-intel is built as a module.

Eric Biggers (2):
  crypto: x86/aes-ctr - rewrite AES-NI optimized CTR and add VAES
    support
  crypto: x86/aes-ctr - remove non-AVX implementation of AES-CTR
