Subject: [PATCH 5/5] powerpc: Remove unused st_le*() and ld_le* functions
Date: Tue, 3 Feb 2015 16:36:25 +1100 [thread overview]
Message-ID: <1422941785-22557-6-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1422941785-22557-1-git-send-email-david@gibson.dropbear.id.au>
The powerpc specific st_le*() and ld_le*() functions in
arch/powerpc/asm/swab.h no longer have any users. They are also
misleadingly named, since they always byteswap, even on a little-endian
host.
This patch removes them.
