From: Laura Abbott Date: Mon, 17 Jun 2013 17:29:12 +0000 (-0700) Subject: ARM: add definitions for pte_mkexec/pte_mknexec X-Git-Tag: next-20131210~99^2^3~3 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=10aa8ecd56198f53baaaf9c7208fd780088c1f71;p=karo-tx-linux.git 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.
