Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
 "The irq department provides:

   - Support for MSI to wire bridges and a first user of it

   - More ACPI support for ARM/GIC

   - A new TS-4800 interrupt controller driver

   - RCU based free of interrupt descriptors to support the upcoming
     Intel VMD technology without introducing a locking nightmare

   - The usual pile of fixes and updates to drivers and core code"
