    Subject[PATCH 0 of 3] MMIO 32-bit copy routine, the final frontier
    After yet more review comments from several people, here is a reworked
    set of 32-bit MMIO copy patches. This may even be the final set.

    These define the generic __raw_memcpy_toio32 as a weak symbol, which
    arches are free to override. We provide a specialised implementation
    for x86_64.

    These patches should apply cleanly against current -git, and have been
    tested on i386 and x86_64.

    The patch series is as follows:

    Introduce the generic MMIO 32-bit copy routine.

    Add memcpy32 routine to x86_64.

    Get each arch to use generic memcpy_io code, except x86_64, which
    uses memcpy32.
