[PATCH] MM: Make needlessly global hugetlb_no_page() static.

  i'm assuming that, given the following:

$ grep -rw hugetlb_no_page *
mm/hugetlb.c:int hugetlb_no_page(struct mm_struct *mm, struct vm_area_struct *vma,
mm/hugetlb.c:           ret = hugetlb_no_page(mm, vma, address, ptep, write_access);

if a routine is both declared and defined in a single translation
unit, and isn't EXPORT_SYMBOLed in some way, that's pretty much the
definition of needlessly global, right?
