From ec7b0339fa408dc5859d0a2e661b5d74683dfd3b Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Wed, 12 Jun 2013 09:38:43 -0700 Subject: [PATCH] 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.
