Subject: [PATCH 0/4] Bugfix + small cleanup to populate_p[mug]d

The first patch fixes a bug in populate_pud, which results in the
requested mapping not being completely installed if the CPU does not
support GB pages.

The next three are small cleanups.

Thanks.

Arvind Sankar (4):
  x86/mm/pat: Handle no-GBPAGES case correctly in populate_pud
  x86/mm/pat: Ensure that populate_pud only handles one PUD
  x86/mm/pat: Propagate all errors out of populate_pud
  x86/mm/pat: Make num_pages consistent in populate_{pte,pud,pgd}
