: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.
