From 387faedb1dee2e917811acd05902cc36142a4850 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Wed, 30 Jan 2008 13:33:04 +0100 Subject: [PATCH] x86 setup: correct the base in the GDT_ENTRY() macro The GDT_ENTRY() macro in pm.c would incorrectly cut the bottom 8 bits off the base. We didn't define any bases with the bottom 8 bits nonzero, so it is a non-manifest bug, but it's still a bug. Pointed out by John Smith . Cc: John Smith Signed-off-by: H.
