x86: Move notify_die from nmi.c to traps.c
In order to handle a new nmi_watchdog approach, I need to move the notify_die() routine out of nmi_watchdog_tick() and into default_do_nmi(). This lets me easily swap out the old nmi_watchdog with the new one with just a config change. The change probably makes sense from a high level perspective because the nmi_watchdog shouldn't be handling notify_die routines anyway. However, this move does change the semantics a little bit. Instead of checking on every nmi interrupt if the cpus are stuck, only check them on the nmi_watchdog interrupts. v2: Move notify_die call into #idef block Signed-off-by: Don Zickus <dzickus@redhat.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: gorcunov@gmail.com Cc: aris@redhat.com Cc: peterz@infradead.org LKML-Reference: <1265424425-31562-2-git-send-email-dzickus@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
