+Subject: [PATCH] paxtest: page alignment ARM and NIOS2 arch
+
+- Extended ARM range from ARMv6-v7 to also include anything below v7
+- Added NIOS2 arch to conditionally have smaller alignment
+
+Submitted Upstream to pageexec@freemail.hu.  Also posted a
+bug to both (Hardened) Suse and Gentoo's bugtrackers.
