From f6dc247cac1a8ee64e59019c3b948d23f3b1a36f Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:12 +0100 Subject: [PATCH] x86: change gdt acessor macro name This patch changes the name of x86_64 macro used to access the per-cpu gdt. It is now equal to the i386 version, which will allow code to be shared.
