This series converts powerpc to generic PTDUMP.

For that, we first need to add missing hugepd support
to pagewalk and ptdump.

v2:
- Reworked the pagewalk modification to add locking and check ops->pte_entry
- Modified powerpc early IO mapping to have gaps between mappings
- Removed the logic that checked for contiguous physical memory
- Removed the articial level calculation in ptdump_pte_entry(), level 4 is ok for all.
- Removed page_size argument to note_page()

Christophe Leroy (4):
  mm: pagewalk: Fix walk for hugepage tables
  powerpc/mm: Leave a gap between early allocated IO areas
  powerpc/mm: Properly coalesce pages in ptdump
  powerpc/mm: Convert powerpc to GENERIC_PTDUMP
