    kernel - Use higher invltlb synchronization timeout if guest
    
    * Increase the invltlb synchronization timeout from 10 seconds
      to 60 seconds if running as a guest.  Just in case the host
      is heavily paging the guest, 10 seconds might not be enough.
    
      Of course, performance will be absolutely terrible if broadcast
      IPIs take that long to synchronize, but there isn't anything
      the guest can do about it.
