From 5dc3055879b8f659f62abb7c3d1eaa4d02e36d65 Mon Sep 17 00:00:00 2001 From: Don Zickus Date: Mon, 29 Nov 2010 17:07:17 -0500 Subject: x86, NMI: Add back unknown_nmi_panic and nmi_watchdog sysctls Originally adapted from Huang Ying's patch which moved the unknown_nmi_panic to the traps.c file. Because the old nmi watchdog was deleted before this change happened, the unknown_nmi_panic sysctl was lost. This re-adds it. Also, the nmi_watchdog sysctl was re-implemented and its documentation updated accordingly.
