Good catch!  I've never realized this problem too.

I think we should have explicit type / size macros for "move" too, like
PTR_MOVE, REG_MOVE, ..., to tell assembler the actual size of operand of
"move".  It's size of pointer (curlwp) for the lock_stubs.S case.

The actual code will be either addu or daddu adding to the zero register.
