From: Harvey Harrison <harvey.harrison@...il.com>
To: Andrew Morton <akpm@...ux-foundation.org>
Cc: Linus Torvalds <torvalds@...ux-foundation.org>,
LKML <linux-kernel@...r.kernel.org>
Subject: [PATCH 01/24] byteorder: update arch override definitions
Linus prefers the actual function name be used as the guard.
Makes it greppable for all places that define/use the __arch
version.
Signed-off-by: Harvey Harrison <harvey.harrison@...il.com>
---
Andrew, an update for byteorder-add-a-new-include-linux-swabh-to-define-byteswapping-functions.patch
Linus expressed his dislike for the HAVE_ARCH_ format as it becomes ungreppable to
see who actually uses it.
New versions of all the arch wire-ups as well, with acks for avr32 and mips from
arch maintainers.
