Well, I'd rather not. If you follow linux-mips, Ralf has been talking
about removing sa_restorer while there are still no uses of it. Can we
kill this bit now?

This comment's also inappropriate. GDB won't handle __restore or
__restore_rt at all. Of course, it doesn't handle signal frames yet
either, but that's just because I'm a bum; I have it working, I just
need to clean it up and commit it.
