which have now been fixed.  So would a simple patch that puts the
_savegpr etc functions in their own section (defined how?) fix this for
us?

Ah, the kernel provides its own save/restore functions, and these get
mashed into a .text containing normal functions with toc references by
ld -r.  Well, you could stop using ld -r.  Otherwise, try

 .section ".text.save.restore","ax",@progbits

OK, so that helped a lot.  Now I get this:

I assume at this point, we are just too large.
