From 851394229e79c11b0b5b74c509817848e9a80564 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Sun, 19 Feb 2012 07:43:09 -0800 Subject: [PATCH] x32: Export setup/restore_sigcontext from signal.c Export setup_sigcontext() and restore_sigcontext() from signal.c, so we can use the 64-bit versions verbatim for x32.
