Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner:
"A small set of fixes for the interrupt subsystem:
- Fix a double increment in the irq descriptor allocator which
resulted in a sanity check only being done for every second
affinity mask
- Add a missing device tree translation in the stm32-exti driver.
Without that the interrupt association is completely wrong.
- Initialize the mutex in the GIC-V3 MBI driver
- Fix the alignment for aliasing devices in the GIC-V3-ITS driver so
multi MSI allocations work correctly
- Ensure that the initial affinity of a interrupt is not empty at
startup time.
- Drop bogus include in the madera irq chip driver
- Fix KernelDoc regression"
