With CONFIG_GENERIC_BUG=n the build fails with: arch/powerpc/kernel/traps.c:1442:5: error: no previous prototype for ‘is_valid_bugaddr’ [-Werror=missing-prototypes] 1442 | int is_valid_bugaddr(unsigned long addr) | ^~~~~~~~~~~~~~~~ The prototype is only defined, and the function is only needed, when CONFIG_GENERIC_BUG=y, so move the implementation under that.
