When neither CONFIG_VSX nor CONFIG_PPC_FPU_REGS are selected, unsafe_copy_fpr_to_user() and unsafe_copy_fpr_from_user() are doing nothing. Then, unless the 'label' operand is used elsewhere, GCC complains about it being defined but not used. To fix that, add an impossible 'goto label'.

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.
