From 6b68f01baa810e9f63fbf39e9d5c3ef1d94a966f Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Wed, 30 Jan 2008 13:31:12 +0100 Subject: x86: unify struct desc_ptr This patch unifies struct desc_ptr between i386 and x86_64. They can be expressed in the exact same way in C code, only having to change the name of one of them. As Xgt_desc_struct is ugly and big, this is the one that goes away. There's also a padding field in i386, but it is not really needed in the C structure definition.
