    powerpc: io: implement dummy relaxed accessor macros for writes · 5da59057
    Will Deacon authored
    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 powerpc, in the
    same vein as the dummy definitions for the relaxed read accessors.
