[PATCH 41/49] x86/alternatives: Simplify and clean up patch_cmp()

[Ingo Molnar]

- No need to cast over to 'struct smp_text_poke_loc *', void * is just fine
  for a binary search,

- Use the canonical (a, b) input parameter nomenclature of cmp_func_t
  functions and rename the input parameters from (tp, elt) to
  (tpl_a, tpl_b).
