From a1bc148c7c81f886426c253f2ea7beb0f301f6b0 Mon Sep 17 00:00:00 2001 From: Doug Zongker Date: Thu, 13 Feb 2014 15:18:19 -0800 Subject: remove 'retouch' ASLR support Older versions of android supported an ASLR system where binaries were randomly twiddled at OTA install time. Remove support for this; we now use the ASLR support in the linux kernel.
