[Qemu-devel] [PATCH 2/3] x86: Raise inter-processor NMI and SMI

[Jan Kiszka]

[ This patch obsoletes
 http://permalink.gmane.org/gmane.comp.emulators.qemu/22989. ]

Make the APIC deliver inter-processor NMI and SMI requests. NMI delivery
was successfully tested in the context of kgdb (Linux kernel debugger),
SMI is included for the sake of completeness.
