Subject: [PATCH 0/2] Arch-specific user pgtables ceiling

Following feedback on the previous patch to limit the free_pgtables()
ceiling, this series introduces a USER_PGTABLES_CEILING macro defaulting
to 0 and an ARM-specific definition to TASK_SIZE.

Catalin Marinas (1):
  arm: Set the page table freeing ceiling to TASK_SIZE

Hugh Dickins (1):
  mm: Allow arch code to control the user page table ceiling
