For reasons that are unclear to this reader fpsimd_bind_state_to_cpu() populates the struct fpsimd_last_state_struct that it uses to store the active floating point state for KVM guests by passing an argument for each member of the structure. As the richness of the architecture increases this is resulting in a function with a rather large number of arguments which isn't ideal. Simplify the interface by using the struct directly as the single argument for the function, renaming it as we lift the definition into the header. This could be built on further to reduce the work we do adding storage for new FP state in various places but for now it just simplifies this one interface.

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.
