Subject: [GIT pull] irq fixes for 3.9

Linus,

please pull the latest irq-urgent-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-urgent-for-linus

* Single bugfix for a wrong return value, which prevents the calling
  function to invoke the software fallback.

Thanks,

	tglx
