This patch set touches too many files, so I didn't send the cover letter
to all maintainers. The whole patch set is to simplify core irq
interfaces by killing the 'irq' parameter. Please refer to
lkml.org/lkml/2015/6/4/113

And it may depends on preceding patches in tip/x86/apic branch, so it
would be safer to handle the patch set altogether.
Thanks!
