Hi Jason,
Today's linux-next build (x86_64 allmodconfig) failed like this:
ERROR: "kgdb_active" [drivers/video/console/fbcon.ko] undefined!
ERROR: "want_console" [drivers/serial/kgdboc.ko] undefined!
ERROR: "last_console" [drivers/serial/kgdboc.ko] undefined!
ERROR: "kgdb_active" [drivers/gpu/drm/drm_kms_helper.ko] undefined!
Caused by various commits from the kgdb tree.
I added this patch for today:
From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Thu, 24 Dec 2009 11:10:41 +1100
Subject: [PATCH] kgdb: export symbols used by modules
