Subject: [PATCH] powerpc: Make unaligned accesses endian-safe for powerpc

From: Anton Blanchard <[email-masked]>
Date: Mon, 16 Dec 2013 18:58:22 +1100

From: Rajesh B Prathipati <[email-masked]>

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.
