 "This is a pretty large diffstat for this time of the release. The main
  culprit is a reorganization of the AMD assembly trampoline, allowing
  percpu variables to be accessed early.

  This is needed for the return stack depth tracking retbleed mitigation
  that will be in 6.2, but it also makes it possible to tighten the IBRS
  restore on vmexit. The latter change is a long tail of the
  spectrev2/retbleed patches (the corresponding Intel change was simpler
  and went in already last June), which is why I am including it right
  now instead of sharing a topic branch with tip.

  Being assembly and being rich in comments makes the line count balloon
  a bit, but I am pretty confident in the change (famous last words)
  because the reorganization actually makes everything simpler and more
  understandable than before. It has also had external review and has
  been tested on the aforementioned 6.2 changes, which explode quite
  brutally without the fix.

  Apart from this, things are pretty normal.

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.
