From 148b50830993acc67129f09c544d9167291e5458 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 6 Jun 2008 03:27:41 +0100 Subject: [PATCH] x86: NMI watchdog: Downgrade helper A downgrade helper for the NMI watchdog to be used in all places where the I/O APIC watchdog may have been requested, but the I/O APIC is found not to be there or meant to be left disabled. This is so that the reconfiguration is cosistent and defined in a single place only. Signed-off-by: Maciej W.
