Are you sure ?

Because "grep -r" shows only

./arch/mips/kernel/traps.c:asmlinkage void do_ri(struct pt_regs *regs)
./arch/mips/kernel/traps.c: do_ri(regs);
./arch/mips/lx/lxRi.c: do_ri(regp);

On my linux-2.4.17_mvl21 kernel. And I'm quite sure that when my kernel
crashes it's not being called from any of these places.

But then again, may be in may case it's getting called only because some
memory get overwritten.

Can anyone please enlighten me about the do_ri function ? I could not
find any reference to what it does and when it's  called anywhere.


 It's called from arch/mips/kernel/entry.S or
arch/mips64/kernel/r4k_genex.S to handle the Reserved Instruction
exception.
