What are the gregset_t/fpregset_t types in your working tree? There
aren't any definitions of them in the only copy of the MIPS code that I
have here, and they've had various bad definitions in glibc until
recently. They also recently changed...
[Although I think your kernel change is the right way to go, here.
Just being cautious.]
