Subject: [PATCH] powerpc: Make unaligned accesses endian-safe for powerpc
Date: Mon, 16 Dec 2013 18:58:22 +1100 [thread overview]
Message-ID: <20131216185822.368c29d1@kryten> (raw)
In-Reply-To: <52A9DA34.40905@linux.vnet.ibm.com>
From: Rajesh B Prathipati <rprathip@linux.vnet.ibm.com>
The generic put_unaligned/get_unaligned macros were made endian-safe by
calling the appropriate endian dependent macros based on the endian type
of the powerpc processor.
