From 530b099dfe8499d639e7fbcad28c4199e2a720c7 Mon Sep 17 00:00:00 2001 From: Colin Cross Date: Tue, 4 Feb 2014 02:15:32 +0000 Subject: [PATCH] security: select correct default LSM_MMAP_MIN_ADDR on arm on arm64 Binaries compiled for arm may run on arm64 if CONFIG_COMPAT is selected. Set LSM_MMAP_MIN_ADDR to 32768 if ARM64 && COMPAT to prevent selinux failures launching 32-bit static executables that are mapped at 0x8000.
