AP startup on PVH follows the PV method, so we need to add a hook in order to diverge from bare metal. Approved by: gibbs Sponsored by: Citrix Systems R&D amd64/amd64/machdep.c: - Add hook for start_all_aps on native (using native_start_all_aps defined in mp_machdep). amd64/amd64/mp_machdep.c: - Make some variables global because they will also be used by the Xen PVH AP startup code. - Use the start_all_aps hook to start APs. - Rename start_all_aps to native_start_all_aps. amd64/include/smp.h: - Add declaration for native_start_all_aps. x86/include/init.h: - Declare start_all_aps hook in init_ops. x86/xen/pv.c: - Pick external declarations from mp_machdep. - Introduce Xen PV code to start APs on PVH. - Set start_all_aps init hook to use the Xen PVH implementation.
