Subject: [patch 1/9] genirq: cleanup mismerge artifact
Date: Fri, 2 Nov 2007 10:37:48 -0700	[thread overview]
Message-ID: <20071102173748.GB6378@kroah.com> (raw)

2.6.22-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: Thomas Gleixner <tglx@linutronix.de>

patch 496634217e5671ed876a0348e9f5b7165e830b20 in mainline.

Commit 5a43a066b11ac2fe84cf67307f20b83bea390f83: "genirq: Allow fasteoi
handler to retrigger disabled interrupts" was erroneously applied to
handle_level_irq().  This added the irq retrigger / resend functionality
to the level irq handler.

Revert the offending bits.
