Subject: [GIT PULL] prot-none fixes for 3.8
Date: Fri, 9 Nov 2012 15:08:23 +0000 [thread overview]
Message-ID: <1352473703-18408-1-git-send-email-will.deacon@arm.com> (raw)
Hi Russell,
This patch series fixes the treatment of PROT_NONE pages for 2-level and
3-level page tables so that the kernel cannot be used to access these
pages on behalf of userspace when !CPU_USE_DOMAINS.
Thanks,
Will
