Hi Joe, hi Ben,
While reviewing some kernel config, I came across
CONFIG_DCACHE_WORD_ACCESS and tried to understand its purpose.
Then, I discovered this RFC patch from 2014 that seems never to have
been integrated:

It seems to duplicate CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
so use that instead.
This changes the !CPU_LITTLE_ENDIAN powerpc arch to use unaligned
accesses in fs/dcache.c and fs/namei.c as
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is enabled for that arch.
Remove the now unused DCACHE_WORD_ACCESS
