From 9c48f1c629ecfa114850c03f875c6691003214de Mon Sep 17 00:00:00 2001 From: Don Zickus Date: Fri, 30 Sep 2011 15:06:21 -0400 Subject: x86, nmi: Wire up NMI handlers to new routines Just convert all the files that have an nmi handler to the new routines. Most of it is straight forward conversion. A couple of places needed some tweaking like kgdb which separates the debug notifier from the nmi handler and mce removes a call to notify_die. [Thanks to Ying for finding out the history behind that mce call https://lkml.org/lkml/2010/5/27/114 And Boris responding that he would like to remove that call because of it https://lkml.org/lkml/2011/9/21/163] The things that get converted are the registeration/unregistration routines and the nmi handler itself has its args changed along with code removal to check which list it is on (most are on one NMI list except for kgdb which has both an NMI routine and an NMI Unknown routine).
