[PATCH] i386: Add machine_ops interface to abstract halting and rebooting

Browse Source 
machine_ops is an interface for the machine_* functions defined in
<linux/reboot.h>.  This is intended to allow hypervisors to intercept
the reboot process, but it could be used to implement other x86
subarchtecture reboots.
