Building eg. 83xx/mpc832x_rdb_defconfig with FPU=n, fails with: arch/powerpc/platforms/83xx/suspend.c: In function 'mpc83xx_suspend_enter': arch/powerpc/platforms/83xx/suspend.c:209:17: error: implicit declaration of function 'enable_kernel_fp' 209 | enable_kernel_fp(); Fix it by providing an enable_kernel_fp() stub for FPU=n builds, which allows using IS_ENABLED(CONFIG_PPC_FPU) around the call to enable_kernel_fp().
