You can use numbers for local (temporary) labels followed by 'f' for
forward or 'b' for back. The instruction bne 4f goes to the label '4'
further down in the program. If it was bne 4b, it would go to the
label '4' previously seen in the file. This is good for short logical
jumps and loops.

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

I mean if 4f is a number , is it number of instructions or number
of bytes or words?
