Subject: [PATCH v2 07/15] MIPS: IP27: clean out sn/nmi.h
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.
