- Fix a large number of x86 Kconfig dependency and help text accuracy
bugs/problems, by Mateusz Jończyk and David Heideberg.
- Fix a VM_PAT interaction with fork() crash. This also touches
core kernel code.
- Fix an ORC unwinder bug for interrupt entries
- Fixes and cleanups.
- Fix an AMD microcode loader bug that can promote verification failures
into success.
- Add early-printk support for MMIO based UARTs on an x86 board that
had no other serial debugging facility and also experienced early
boot crashes.

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 reStructuredText 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.
