From 86d78f640257344cc90a50da8cd52297ba1c6bdf Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Tue, 22 Apr 2008 16:28:41 +0100 Subject: [PATCH] x86: fix watchdog ops for CoreDuo There apparently was an unnoticed conflict between an earlier patch to this file and mine (d1e084746b0e5806e6345ab31c5b370f8dee2b23), which I noticed only now. I suppose a change like the one below (untested) is needed; I didn't get any response on a confirmation request for this from the submitter of the first patch. The issue is the writing of the 'checkbit' member at the end of setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops rather than wd_ops.
