From 2f083481cfd38320ebde0b83d836b967a2419d53 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Wed, 4 Sep 2013 11:34:08 +0100 Subject: parisc: io: implement dummy relaxed accessor macros for writes write{b,w,l,q}_relaxed are implemented by some architectures in order to permit memory-mapped I/O accesses with weaker barrier semantics than the non-relaxed variants. This patch adds dummy macros for the write accessors to parisc, in the same vein as the dummy definitions for the relaxed read accessors.
