From 3ed3f06295e69700fa808396f7b350bff2b69de0 Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Wed, 4 Jun 2008 01:00:47 +0400 Subject: x86: nmi - consolidate nmi_watchdog_default for 32bit mode 64bit mode bootstrap code does set nmi_watchdog to NMI_NONE by default and doing the same on 32bit mode is safe too. Such an action saves us from several #ifdef. Btw, my previous commit commit 19ec673ced067316b9732bc6d1c4ff4052e5f795 Author: Cyrill Gorcunov Date: Wed May 28 23:00:47 2008 +0400 x86: nmi - fix incorrect NMI watchdog used by default did not fix the problem completely, moreover it introduced additional bug - nmi_watchdog would be set to either NMI_LOCAL_APIC or NMI_IO_APIC _regardless_ to boot option if being enabled thru /proc/sys/kernel/nmi_watchdog. Sorry for that. Fix it too.
