From d571cd18f225542460b5d9b83e5e0d507be71656 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 6 Jan 2006 00:18:53 -0800 Subject: [PATCH] [PATCH] uml: Move mconsole support out of generic code A bit of restructuring which eliminates the all_allowed argument (which is mconsole-specific) to line_setup. That logic is moved to the mconsole callback.
