Subject: [PATCH 0/5] crypto: chacha20 - Alignment fixes

From: Eric Biggers <ebiggers@...gle.com>

This series fixes potentially unaligned memory accesses when loading the
initial state, key, and IV for ChaCha20, and when outputting each
keystream block.

It also removes the cra_alignmask from the generic and x86 ChaCha20
implementations, once it is no longer needed.

Eric Biggers (5):
  crypto: chacha20 - Fix unaligned access when loading constants
  crypto: chacha20 - Use unaligned access macros when loading key and IV
  crypto: chacha20 - Remove cra_alignmask
  crypto: x86/chacha20 - Remove cra_alignmask
  crypto: chacha20 - Fix keystream alignment for chacha20_block()
