This allows the compiler to verify the format strings vs the types of the arguments. Update the other prototype declarations in asm/xmon.h. Silence warnings (triggered at W=1) by adding relevant __printf attribute. Move #define at bottom of the file to prevent conflict with gcc attribute. Solves the original warning: arch/powerpc/xmon/nonstdio.c:178:2: error: function might be possible candidate for ‘gnu_printf’ format attribute In turn this uncovered many formatting errors in xmon.c, all fixed in this patch.
