* pagemap: pass mm into pagewalkersDave Hansen2008-06-121-20/+22
| | | | | | | | | | | | | We need this at least for huge page detection for now, because powerpc needs the vm_area_struct to be able to determine whether a virtual address is referring to a huge page (its pmd_huge() doesn't work). It might also come in handy for some of the other users.

* mm: fix possible off-by-one in walk_pte_range()Johannes Weiner2008-04-281-2/+6
| | | | | | | | | | | | | | | | After the loop in walk_pte_range() pte might point to the first address after the pmd it walks. The pte_unmap() is then applied to something bad.
