Subject: [PATCH 0/2] Arch-specific user pgtables ceiling
Date: Mon, 18 Feb 2013 16:18:29 +0000 [thread overview]
Message-ID: <1361204311-14127-1-git-send-email-catalin.marinas@arm.com> (raw)
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
