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 interrupt departement delivers this time:
- New infrastructure to manage NMIs on platforms which have a sane
NMI delivery, i.e. identifiable NMI vectors instead of a single
lump.
- Simplification of the interrupt affinity management so drivers
don't have to implement ugly loops around the PCI/MSI enablement.
- Speedup for interrupt statistics in /proc/stat
- Provide a function to retrieve the default irq domain
- A new interrupt controller for the Loongson LS1X platform
- Affinity support for the SiFive PLIC
- Better support for the iMX irqsteer driver
- NUMA aware memory allocations for GICv3
- The usual small fixes, improvements and cleanups all over the
place"
