Pull more RISC-V updates from Palmer Dabbelt:
"There's still a handful of new features in here, but there are a lot
of fixes/cleanups as well:
- Support for the Zicbom extension for explicit cache-block
management, along with the necessary bits to make the non-standard
cache management ops on the Allwinner D1 function
- Support for the Zihintpause extension, which codifies a go-slow
instruction used for cpu_relax()
- Support for the Sstc extension for supervisor-mode timer/counter
management
- Many device tree fixes and cleanups, including a large set for the
Canaan device trees
- A handful of fixes and cleanups for the PMU driver"

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.
