Pros of the alternative version:
- No #ifdefs in .c files.

Cons of the alternative version:
- For this code (assuming QE=n):
        if ((np = of_find_node_by_name(NULL, "par_io")) != NULL)
		par_io_init(np);

  GCC can still issue the of_find_node_by_name() call. (I wonder if
  there is any way to tell gcc that particular function doesn't
  produce any side-effects so that gcc can optimize it away too).

It's up to you to decide which version you want to merge.
