From f9a535e089abcbc7ac99db83c8c6e4644e395b12 Mon Sep 17 00:00:00 2001 From: Xu Wang Date: Thu, 5 Feb 2015 18:28:35 +0800 Subject: nmi: Implement inject_nmi() for non-monitor context use Let's introduce a general "inject_nmi()" function that doesn't rely on the cpu index of the monitor, but uses cpu index 0 as default (except for x86). This function can then later be used from a non-monitor context.
