From fbd5577901388ff9306a05eb63648c30e4722134 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Tue, 7 Feb 2006 12:58:40 -0800 Subject: [PATCH] [PATCH] uml: add debug switch for skas mode It doesn't do anything but emit a warning, but there's a user population that's used to adding 'debug' to the UML command line in order to gdb it. With skas0 mode, that's not necessary, but these users need some indication that 'debug' doesn't do what they want.
