Merge branch 'jn/block-sha1'
The code to load a word one-byte-at-a-time was optimized into a
word-wide load instruction even when the pointer was not aligned,
which caused issues on architectures that do not like unaligned
access.
* jn/block-sha1:
Makefile: BLK_SHA1 does not require fast htonl() and unaligned loads
block-sha1: put expanded macro parameters in parentheses
block-sha1: avoid pointer conversion that violates alignment constraints
