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"
