From d010da312e05ef8543f6e176d14bcb68a7c369e0 Mon Sep 17 00:00:00 2001
From: Andrew Pinski <apinski@cavium.com>
Date: Mon, 27 Oct 2014 00:59:50 -0700
Subject: [PATCH 27/32] Add sigstack.h header for ILP32 reasons.
ILP32 uses the same structure layout for sigaltstack as
LP64 so we need a special header file.
* sysdeps/unix/sysv/linux/aarch64/bits/sigstack.h: New file.
