The BSP will be marked as initialised after hvm_load_cpu_ctxt has loaded the
initial state, which is called from the toolstack during domain creation.
Previous to my HVMlite series HVM guests were started without setting any
explicit CPU state (in fact we placed that horrible jmp at 0x0, because the
IP was by default set to 0x0). This is no longer true, and now HVM guests
require that a proper CPU context is loaded before starting. This change
helps enforce this policy.
