    kernel - Bring in dff23c692 from FreeBSD
    
    Bring in a commit further strengthening iret/%gs handling.  FreeBSD also
    made a followup commit that fixes their signal handler for stack faults
    which we already effectively implement and did not need.
    
    Original commit message is
    
        The #ss fault handler erronously does not check for the fault
        originated from the return to usermode. #ss must be handled same as
        #np.
