[PATCH v2 0/7] s390x/mmu: DAT translation rewrite

Posted by David Hildenbrand 4 years, 6 months ago

This is a split-up of:
    [PATCH-for-4.2 v1 3/9] s390x/mmu: DAT translation rewrite
Rebased on latest upstream changes. Hopefully, this makes it easier to
review.

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 boguous 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
