Switch to the more abstract 'scoped_ksimd()' API, which will be modified in a future patch to transparently allocate a kernel mode FP/SIMD state buffer on the stack, so that kernel mode FP/SIMD code remains preemptible in principe, but without the memory overhead that adds 528 bytes to the size of struct task_struct.

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 reStructuredText 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.
