This is a split-up of:
    [PATCH-for-4.2 v1 3/9] s390x/mmu: DAT translation rewrite
Rebased on latest upstream changes.

v3 -> v4:
- "s390x/mmu: Inject PGM_ADDRESSING on bogus table addresses"
-- s/goguous/bogus/
- "s390x/mmu: DAT table definition overhaul"
-- Fix SEGMENT_ENTRY_SFAA
-- Drop three unnecessary defines
- "s390x/mmu: Convert to non-recursive page table walk"
-- Reorder "REGION_ENTRY_P" checks
-- Drop default cases that cannot be reached

v2 -> v3:
- "s390x/mmu: Inject PGM_ADDRESSING on boguous table addresses"
-- Keep using cs->as
-- Make read_table_entry() return true/false
- "s390x/mmu: DAT table definition overhaul"
-- Added a comment where to find details about s390x and used definitions

v1 -> v2:
- Cleanup old code first, before switching to non-recursive handling
- Fix EDAT1 translation: I was missing the vaddr offset within the 1MB
  page.

David Hildenbrand (7):
  s390x/mmu: Drop debug logging from MMU code
  s390x/mmu: Move DAT protection handling out of mmu_translate_asce()
  s390x/mmu: Inject DAT exceptions from a single place
  s390x/mmu: Inject PGM_ADDRESSING on bogus table addresses
  s390x/mmu: Use TARGET_PAGE_MASK in mmu_translate_pte()
  s390x/mmu: DAT table definition overhaul
  s390x/mmu: Convert to non-recursive page table walk
