[GIT pull] irq fixes for 3.17

[Thomas Gleixner]

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

Another pile of ARM specific irq chip fixlets:
 - Off by one bugs in the crossbar driver
 - Missing annotations
 - A bunch of "make it compile" updates

I pulled the lot today from Jason, but it has been in -next for at
least a week.

Thanks,

	tglx
