Subject: Make asm/word-at-a-time.h available on all architectures

From: Chris Metcalf <[email protected]>

commit a6e2f029ae34f41adb6ae3812c32c5d326e1abd2 upstream.

Added the x86 implementation of word-at-a-time to the generic version, which previously only supported big-endian.

Omitted the x86-specific load_unaligned_zeropad(), which in any case is also not present for the existing BE-only implementation of a word-at-a-time, and is only used under CONFIG_DCACHE_WORD_ACCESS.

Added as a "generic-y" to the Kbuilds of all architectures that didn't previously have it.
