From: Laura Abbott Date: Mon, 17 Jun 2013 17:29:12 +0000 (-0700) Subject: ARM: add definitions for pte_mkexec/pte_mknexec X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=27ec8da4ace46900a71b8462157aa2bc88ff5d2c;p=~andy%2Flinux ARM: add definitions for pte_mkexec/pte_mknexec Other architectures define pte_mkexec to mark a pte as executable. Add pte_mkexec for ARM to get the same functionality. Although no other architectures currently define it, also add pte_mknexec to explicitly allow a pte to be marked as non executable.
