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"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
