Can we just call it "MMU" ?
I don't think it's entirely clear what "translation" means here if you
don't already know.
cheers
I avoided using MMU, because it will confuse hardware guys. Radix is not
clearly the full definition of
Memory management unit, but rather the translation mode used by memory
management unit. But
i don't have strong opinion on this.
Do you want me to send an updated patch ? or you can update it when you
apply it to your tree ?
