    alpha: add full ioread64/iowrite64 implementation · e19d4ebc
    Arnd Bergmann authored
    The previous patch introduced ioread64/iowrite64 declarations, but
    this means we no longer get the io-64-nonatomic variant, and
    run into a long error when someone actually wants to use these:
    
    ERROR: modpost: "ioread64" [drivers/net/ethernet/freescale/enetc/fsl-enetc.ko] undefined!
    
    Add the (hopefully) correct implementation for each machine type,
    based on the 32-bit accessor. Since the 32-bit return type does
    not work for ioread64(), change the internal implementation to use
    the correct width consistently, but leave the external interface
    to match the asm-generic/iomap.h header that uses 32-bit or 64-bit
    return values.
