this patch is against 2.6.25


when compile 2.6.25 on ia64, following warnings was outputed.

  CC      mm/pagewalk.o
mm/pagewalk.c: In function 'walk_page_range':
mm/pagewalk.c:111: warning: passing argument 1 of 'pgd_offset' discards qualifiers from p\
ointer target type

the type of mm argument of walk_page_range() is "const struct mm *",
but pgd_offset() on ia64 declare "struct mm*".
cris port has the same problems.

I propse add const to pgd_offset() for solve this problem.

Thanks!
