From 4038f901cf102a40715b900984ed7540a9fa637f Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Tue, 26 Sep 2006 10:52:27 +0200 Subject: [PATCH] i386/x86-64: Fix NMI watchdog suspend/resume Making NMI suspend/resume work with SMP. We use CPU hotplug to offline APs in SMP suspend/resume. Only BSP executes sysdev's .suspend/.resume method. APs should follow CPU hotplug code path. And: +From: Don Zickus Makes the start/stop paths of nmi watchdog more robust to handle the suspend/resume cases more gracefully.
