This reverts commit 020eb3daab.
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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
