[ Upstream commitc7e0d9bb91] Clang 17 reports: arch/powerpc/kernel/traps.c:1167:19: error: unused function '__parse_fpscr' [-Werror,-Wunused-function] __parse_fpscr() is called from two sites. First call is guarded by #ifdef CONFIG_PPC_FPU_REGS Second call is guarded by CONFIG_MATH_EMULATION which selects CONFIG_PPC_FPU_REGS. So only define __parse_fpscr() when CONFIG_PPC_FPU_REGS is defined.

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.
