[PATCH 33/49] x86/alternatives: Move the text_poke_array manipulation into text_poke_int3_loc_init() and rename it to __smp_text_poke_batch_add()

[Ingo Molnar]

This simplifies the code and code generation a bit:

   text	   data	    bss	    dec	    hex	filename
  14802	   1029	   4112	  19943	   4de7	alternative.o.before
  14784	   1029	   4112	  19925	   4dd5	alternative.o.after
