Correct.

From arch/mips/Kconfig

config CPU_MIPS32
  bool "MIPS32"
  select CPU_SUPPORTS_32BIT_KERNEL
  select CPU_HAS_PREFETCH

I'll try turning it off directly in the memcpy function.

That's certainly a hack - but likely to result in the best performance.
It's the quickest way to find out if it's the problem I'm seeing. It appears to be. Now, what's the best way to fix this for real?
