Now that we are recording the type of floating point register state we are saving when we write the register state out to memory we can use that information when we load from memory to decide which format to load, bringing TIF_SVE into line with what we saved rather than relying on TIF_SVE to determine what to load. The SME state details are already recorded directly in the saved SVCR and handled based on the information there. Since we are not changing any of the save paths there should be no functional change from this patch, further patches will make use of this to optimise and clarify the code.

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.
