:In this piece of code:
:------------------------------------
:ENTRY(default_halt)
:sti
:#ifndef SMP
:hlt                                     /* XXX:  until a wakeup IPI */
:#ifdef SMP
:#ifdef CHEAP_TPR
:movl    $0, lapic_tpr
:#else
:andl    $~APIC_TPR_PRIO, lapic_tpr
:#endif /** CHEAP_TPR */
:#endif
:hlt
:ret

    Umm... where'd you get the above code?   This is not the current
    halt code for 3.x, 4.x, or 5.x.
