Subject: [GIT Pull] irq updates for 3.14

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

This contains:
     * A bugfix for a long standing waitqueue race
     * A trivial fix for a missing include

Thanks,

	tglx
