The only user is arch/mips/sgi-ip27/ip27-nmi.c;
this file was imported wholesale in 2.3.99pre9-1,
and received only whitespace updates since then

NMI_MAGIC isn't a magic number; it's unclear if it's actually used
by the firmware in some capacity or if it's a holdover from copying
the SGI code, but in the former case it's API
and in the latter it's dead cruft

Lack of QEMU support makes this unvalidatable without the hardware,
so leave it in
