    exit: Add and use make_task_dead. · 0e25498f
    Eric W. Biederman authored
    There are two big uses of do_exit.  The first is it's design use to be
    the guts of the exit(2) system call.  The second use is to terminate
    a task after something catastrophic has happened like a NULL pointer
    in kernel code.
    
    Add a function make_task_dead that is initialy exactly the same as
    do_exit to cover the cases where do_exit is called to handle
    catastrophic failure.  In time this can probably be reduced to just a
    light wrapper around do_task_dead. For now keep it exactly the same so
    that there will be no behavioral differences introducing this new
    concept.
    
    Replace all of the uses of do_exit that use it for catastraphic
    task cleanup with make_task_dead to make it clear what the code
    is doing.
    
    As part of this rename rewind_stack_do_exit
    rewind_stack_and_make_dead.
