From 2a6648e65a2939b80c44262975176a15bac3a75e Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 30 Jan 2008 13:33:01 +0100 Subject: x86: : boot GDT entries are 32/64-independent The boot GDT entries are common between 32- and 64-bit mode, so move them to common code instead of having two identical copies.
