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 department provides:

  Core updates:

   - Better spreading to NUMA nodes in the affinity management

   - Support for more than one set of interrupts to spread out to allow
     separate queues for separate functionality of a single device.

   - Decouple the non queue interrupts from being managed. Those are
     usually general interrupts for error handling etc. and those should
     never be shut down. This also a preparation to utilize the
     spreading mechanism for initial spreading of non-managed interrupts
     later.

   - Make the single CPU target selection in the matrix allocator more
     balanced so interrupts won't accumulate on single CPUs in certain
     situations.

   - A large spell checking patch so we don't end up fixing single typos
     over and over.

  Driver updates:

   - A bunch of new irqchip drivers (RDA8810PL, Madera, imx-irqsteer)

   - Updates for the 8MQ, F1C100s platform drivers

   - A number of SPDX cleanups

   - A workaround for a very broken GICv3 implementation on msm8996
     which sports a botched register set.

   - A platform-msi fix to prevent memory leakage

   - Various cleanups"
