  SVN rev 198245 on 2009-10-19 19:14:04Z by gallatin
  
  MFC of 178042 to allow safe firmware(9) loading from NIC watchdog handlers.
       Also MFCed are the related changes 178016, 183614 and 184842.
  
  178042: Do firmare image loading in a context known to have a root directory
  183614: Dynamically allocate the task struct in firmware mountroot
  184842: Avoid scheduling firmware taskqueues when cold
  178016: Add a mountroot event handler.  Removal of SI_SUB_MOUNT_ROOT
          was not merged.  178042 is dependant upon this.
  
  This fixes a panic in at least mxge(4) if the NIC has a hardware fault
  when the firmware image is not resident.
