The uapi/linux/audit.h header is going to use EM_ARC in order to define AUDIT_ARCH_ARC which is needed to implement syscall_get_arch() which in turn is required to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request. The value for EM_ARC has been taken from http://www.sco.com/developers/gabi/2012-12-31/ch4.eheader.html Signed-off-by: Dmitry V.
