#     powerpc: Only define __parse_fpscr() when required
#     
#     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.
