Revert "x86/ioapic: Restore IO-APIC irq_chip retrigger callback"
commit d966564fcdc19e13eb6ba1fbe6b8101070339c3d upstream.
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.
