It was removed quite a while ago on the [nisimura-pmax-wscons]
branch, and made obsolete on the main tree by Castor's work.
My goal was only to make the pmax part of the [nisimura] branch
work with the mainline arch/mips sources. The conflict had to
be resolved in one or the other way, so I've continued into this
direction instead of taking back changes done on the branch.

Maybe - otoh the different flavours of asm.h macros might
be a more serious problem.
Perhaps Tohru / Castor can comment on this?
