i have to handle a NMI interrupt in bootloader(0xBFC00000),
 and i want to return to linux after the NMI interrupt,  i think other
regs maybe be useing by linux-kernel, i think the NMI handle only can
use K0, K1.

and i do not find the use of K0, K1 in linux-kernel interrupt or
exception handle
so i think if the NMI interrupt a linux interrupt handle, there is
still no conflict.

i am not sure my thinking is right, anyone can give some hints?

Best regards
