Subject: [PATCH 1/6] PPC: Add asm helpers for BE 32bit load/store
Date: Wed, 11 Jun 2014 12:33:46 +0200 [thread overview]
Message-ID: <1402482831-8941-2-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1402482831-8941-1-git-send-email-agraf@suse.de>
>From assembly code we might not only have to explicitly BE access 64bit values,
but sometimes also 32bit ones. Add helpers that allow for easy use of lwzx/stwx
in their respective byte-reverse or native form.
