From 26048d75e8d6c840742468667f4a7ab8c2df74c9 Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:14 +0100 Subject: [PATCH] x86: use the same data type for tls_array. This patch changes the type of tls_array in x86_64 to a desc_struct. Now, both i386 and x86_64 tls_array have the same type, and code accessing it can be shared.
