From: Andy Lutomirski <luto@xxxxxxxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit 81f49a8fd7088cfcb588d182eeede862c0e3303e upstream. is_compat_task() is the wrong check for audit arch; the check should be is_ia32_task(): x32 syscalls should be AUDIT_ARCH_X86_64, not AUDIT_ARCH_I386. CONFIG_AUDITSYSCALL is currently incompatible with x32, so this has no visible effect.
