In arch/ppc/kernel/head.S, there are lines looks like bne 4f or b 5f, I know they are branch instructions, but what about 4f or 5f. Are they the relative length? and what is the unit, I mean if 4f is a number , is it number of instructions or number of bytes or words? ** Sent via the linuxppc-embedded mail list.
