[PATCH] i386: Kdump i386 nmi event notification fix
After a crash we should wait for NMI IPI event and not for external NMI or NMI watchdog tick. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Signed-off-by: Andi Kleen <ak@suse.de> Cc: Don Zickus <dzickus@redhat.com> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org>
