Perhaps I'm missing something obvious, but is there some reason why you
can't just reuse the crash_setup_regs() code? MIPS doesn't implement it
presumably because it's lacking kexec crash kernel support, but it would
make sense to make current ptregs saving more generic if there are going
to be multiple users for it.
