Date: Thu, 17 Apr 2014 14:44:09 +0100 From: Will Deacon <will.deacon@....com> To: linux-arch@...r.kernel.org, linux-kernel@...r.kernel.org Cc: arnd@...db.de, monstr@...str.eu, dhowells@...hat.com, broonie@...aro.org, benh@...nel.crashing.org, peterz@...radead.org, paulmck@...ux.vnet.ibm.com, Will Deacon <will.deacon@....com> Subject: [PATCH 06/18] frv: io: implement dummy relaxed accessor macros for writes write{b,w,l}_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 frv, in the same vein as the dummy definitions for the relaxed read accessors.
