    vkernel - Fix a vkernel lockup on startup
    - During ap_init() any pending IPIs is processed manually so
      clear gd_npoll as the real kernel does.
    - Do not disable interrupts for vkernels during lwkt_send_ipiq3()
      because they don't seem to be re-enabled afterwards as they should.
      I'm not entirely sure this is the right fix, more investigation
      is required.
