    Subject[PATCH] alpha: add io{read,write}{16,32}be functions
    These functions are used in some PCI drivers with big-endian
    MMIO space.

    Admittedly it is almost certain that no one this side of the
    Moon would use such a card in an Alpha but it does get us
    closer to being able to build allyesconfig or allmodconfig,
    and it enables the Debian default generic config to build.
