Linus Torvalds 8a8ca83ec3 Perf updates:
Core:
 
    - Better handling of page table leaves on archictectures which have
      architectures have non-pagetable aligned huge/large pages.  For such
      architectures a leaf can actually be part of a larger entry.
 
    - Prevent a deadlock vs. exec_update_mutex
 
  Architectures:
 
    - The related updates for page size calculation of leaf entries
 
    - The usual churn to support new CPUs
 
    - Small fixes and improvements 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.
