[PATCH V2 5/9] x86/alternative: Split text_poke_bp() into tree steps

text_poke_bp() updates instructions on live kernel on SMP in three steps: 1) add a int3 trap to the address that will be patched 2) update all but the first byte of the patched range 3) replace the first byte (int3) by the first byte of This patch creates one function for each of these steps.
