Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner:
"This udpate delivers:
- A fix for dynamic interrupt allocation on x86 which is required to
exclude the GSI interrupts from the dynamic allocatable range.
This was detected with the newfangled tablet SoCs which have GPIOs
and therefor allocate a range of interrupts. The MSI allocations
already excluded the GSI range, so we never noticed before.
- The last missing set_irq_affinity() repair, which was delayed due
to testing issues
- A few bug fixes for the armada SoC interrupt controller
- A memory allocation fix for the TI crossbar interrupt controller
- A trivial kernel-doc warning fix"
