Subject: [PATCH 0/3] crypto: x86/crc32c - jump table elimination and other cleanups

This series cleans up the x86_64 assembly implementation of CRC32C to
reduce code size, improve performance, and eliminate the use of the
outdated and problematic jump table idiom.

Eric Biggers (3):
  crypto: x86/crc32c - simplify code for handling fewer than 200 bytes
  crypto: x86/crc32c - access 32-bit arguments as 32-bit
  crypto: x86/crc32c - eliminate jump table and excessive unrolling
