    ia64: io: implement dummy relaxed accessor macros for writes · f6b3b7a9
    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 ia64, which may
    be able to be optimised in a similar manner to the relaxed read
    accessors at a later date.
