In subsequent patches, we'll want to make use of sve_user_enable() and sve_user_disable() outside of kernel/fpsimd.c. Let's move these to <asm/fpsimd.h> where we can make use of them. To avoid ifdeffery in sequences like: if (system_supports_sve() && some_condition) sve_user_disable(); ... empty stubs are provided when support for SVE is not enabled. Note that system_supports_sve() contains as IS_ENABLED(CONFIG_ARM64_SVE), so the sve_user_disable() call should be optimized away entirely when CONFIG_ARM64_SVE is not selected. To ensure that this is the case, the stub definitions contain a BUILD_BUG(), as we do for other stubs for which calls should always be optimized away when the relevant config option is not selected. At the same time, the include list of <asm/fpsimd.h> is sorted while adding <asm/sysreg.h>.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
