So I'm starting bootstrap...
And bootstrap fails with:

undefined reference to `__builtin_prefetch'
So something wrong seems to be with this patch.
Oh, yes, that needs to be protected or removed, I'll do this, it'll be
in my next rev. In the mean time, #if 0 it and you can continue.
Those actually speed up the routine by 23%, so I do want to keep them

Thanks for the feedback.
