When kernel mode NEON was first introduced to the arm64 kernel, every call to kernel_neon_begin()/_end() stacked resp. unstacked the entire NEON register file, making it worthwile to reduce the number of used NEON registers to a bare minimum, and only stack those. kernel_neon_begin_partial() was introduced for this purpose, but after the refactoring for SVE and other changes, it no longer exists and was simply #define'd to kernel_neon_begin() directly. In the mean time, all users have been updated, so let's remove the fallback macro.

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.
