    Revert "x86/ioapic: Restore IO-APIC irq_chip retrigger callback"
    
    This reverts commit 020eb3daaba2857b32c4cf4c82f503d6a00a67de.
    
    Gabriel C reports that it causes his machine to not boot, and we haven't
    tracked down the reason for it yet.  Since the bug it fixes has been
    around for a longish time, we're better off reverting the fix for now.
    
    Gabriel says:
     "It hangs early and freezes with a lot RCU warnings.
    
      I bisected it down to :
    
      > Ruslan Ruslichenko (1):
      >       x86/ioapic: Restore IO-APIC irq_chip retrigger callback
    
      Reverting this one fixes the problem for me..
    
      The box is a PRIMERGY TX200 S5 , 2 socket , 2 x E5520 CPU(s) installed"
    
    and Ruslan and Thomas are currently stumped.
