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.
