2.6.22-stable review patch. If anyone has any objections, please let us
know.
------------------
From: Thomas Gleixner <[email protected]>
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.
