commit 849892cd25de32738aad6446217eff7684bcdf6a

    powerpc/64: Use optimized checksum routines on little-endian
    
    Currently we have optimized hand-coded assembly checksum routines for
    big-endian 64-bit systems, but for little-endian we use the generic C
    routines. This modifies the optimized routines to work for
    little-endian. With this, we no longer need to enable
    CONFIG_GENERIC_CSUM. This also fixes a couple of comments in
    checksum_64.S so they accurately reflect what the associated instruction
    does.
