Also, for FRV, I think calling memmove/memcpy for MMU kernels may be the wrong thing to do... I'm sort of leaning towards doing the same thing as NOMMU kernels and just using your inline ones. The advantage of the inline ones is that they are quicker and probably involve fewer instructions executed; whereas using memcpy/memmove may end up with smaller, but slower code. Hmmm... Maybe key on CONFIG_CC_OPTIMIZE_FOR_SIZE?
