That could be. I have no idea what percentage of powerpc 32 bit systems
are mac versus other systems. The ones I have worked with are likely
not a representative sample at all given no macs were involved.
I am not saying don't make the change, I am just asking if the potential
impact is worth it. It could very well be the answer is yes.

I wouldn't. The code may very well predate the VMAP_STACK support.
Adding VMAP_STACK would be unrelated to the broken code, but does affect
it of course in an unfortunate way. So you probably need the person
that wrote the now broken assembly code to fix it, even though when it
was written there was probably nothing wrong with it.
