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. Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202309210327.WkqSd5Bq-lkp@intel.com/ Fixes: b6254ced4da6 ("powerpc/signal: Don't manage floating point regs when no FPU") Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/5de2998c57f3983563b27b39228ea9a7229d4110.1695385984.git.christophe.leroy@csgroup.eu
