Linus Torvalds db020be9f7 Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner:

 - Consolidation of softirq pending:

   The softirq mask and its accessors/mutators have many implementations
   scattered around many architectures. Most do the same things
   consisting in a field in a per-cpu struct (often irq_cpustat_t)
   accessed through per-cpu ops. We can provide instead a generic
   efficient version that most of them can use. In fact s390 is the only
   exception because the field is stored in lowcore.

 - Support for level!?! triggered MSI (ARM)

   Over the past couple of years, we've seen some SoCs coming up with
   ways of signalling level interrupts using a new flavor of MSIs, where
   the MSI controller uses two distinct messages: one that raises a
   virtual line, and one that lowers it. The target MSI controller is in
   charge of maintaining the state of the line.

   This allows for a much simplified HW signal routing (no need to have
   hundreds of discrete lines to signal level interrupts if you already
   have a memory bus), but results in a departure from the current idea
   the kernel has of MSIs.

 - Support for Meson-AXG GPIO irqchip

 - Large stm32 irqchip rework (suspend/resume, hierarchical domains)

 - More SPDX conversions

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
