Linus,

John Levon suggested I send this to you.  It's a cleanup of the NMI 
handling to make it into a request/release mechanism (instead of 
hard-coding everything into traps.c).  It renames "nmi.c" to 
"nmi_watchdog.c" (as it should be named) and moves the real NMI handling 
code from traps.c to nmi.c.  It's been posted and reworked on lkml, and 
it seems to have finally met approval.  The "cc-ed" people have reviewed 
the patch (or at least made helpful suggestions :-).

Since a lot of things are hacking into this code (lkcd, kdb, oprofile, 
nmi watchdog, and now my IPMI watchdog pretimeout), it would be very 
nice to get their junk out of this code and allow them to bind in 
nicely, and allow binding from modules.

(And this time it's a -p1 diff)

Thanks,

-Corey
