The recently introduced page walker (walk_page_range()) calls pgd_offset with a
const struct mm_struct pointer, causing the following compile warning on m68k:
mm/pagewalk.c:111: warning: passing argument 1 of 'pgd_offset' discards qualifiers from pointer target type
Make the `mm' parameter of the inline function pgd_offset() const to shut it
up.

As cris also uses an inline function, I expect a similar warning to show up
there. All other archs use a macro to define pgd_offset.
