Linus Torvalds 3f614ab563 Interrupt core and drivers updates:
- Core:
 
    - Add tracepoints for tasklet callbacks which makes it possible to
      analyze individual tasklet functions instead of guess working
      from the overall duration of tasklet processing
 
    - Ensure that secondary interrupt threads have their affinity adjusted
      correctly.
 
  - Drivers:
 
    - A large rework of the RISC-V IPI management to prepare for a new
      RISC-V interrupt architecture
 
    - Small fixes and enhancements all over the place
 
    - Removal of support for various obsolete hardware platforms and the
      related code

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.
