That's not a very useful comment. How about something like:

  /*
   * Also fault over nearby ptes from within the same pmd and vma,
   * in order to minimize the overhead from page fault exceptions
   * and TLB flushes.
   */
There's no TLB flushes here. But I'm fine with the other part so 
I've updated the comment to say:

/*
 * Also fault over nearby ptes from within the same pmd and vma,
 * in order to minimize the overhead from page fault exceptions:
 */

Thanks,

	Ingo
