Originally sent only to the arm-linux list - now including linux-crypto.
Ard suggested that Herbert take the series.

This series completes the arm64 crc32 helper acceleration by adding crc32_be.

There are plenty of users, for example OF.

To compensate for the extra supporting cruft in lib/crc32.c, a couple of minor
tidies.

changes since v2:
- no code change, but sent to Herbert+crypto with Catalin's ack for arm64

changes since v1:
- assembler style fixes from Ard's review

Kevin Bracey (4):
  lib/crc32.c: remove unneeded casts
  lib/crc32.c: Make crc32_be weak for arch override
  lib/crc32test.c: correct printed bytes count
  arm64: accelerate crc32_be

All applied.  Thanks.
