From d89be56b2153ccad7e8cd9e71b5d8b686632e8c2 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 8 Sep 2009 23:29:16 -0700 Subject: [PATCH] sparc64: Make touch_nmi_watchdog() actually work. It guards it's actions on nmi_watchdog_active, but nothing ever sets that and it's initial value is zero. Signed-off-by: David S.
