- Differentiate which aspects of the FPU state get saved/restored when the FPU
is used in-kernel and fix a boot crash on K7 due to early MXCSR access before
CR4.OSFXSR is even set.
- A couple of noinstr annotation fixes
- Correct die ID setting on AMD for users of topology information which need
the correct die ID
- A SEV-ES fix to handle string port IO to/from kernel memory properly

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.
