The function names for xsave[s]/xrstor[s] operations are horribly named and a permanent source of confusion. Rename: copy_xregs_to_user() to xsave_to_user_sigframe() copy_user_to_xregs() to xrstor_from_user_sigframe() so it's entirely clear what this is about. This is also a clear indicator of the potentially different storage format because this is user ABI and cannot use compacted format. No functional change.

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.
