From 5faae2e5d1f53df9dce482032c8486bc3a1feffc Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 16 Apr 2008 13:51:49 +1000 Subject: [PATCH] [POWERPC] Always add preferred consoles in platforms/pseries/lpar.c There is logic in platforms/peries/lpars.c which checks if the user has specified a console on the command line, and refrains from adding a preferred console entry for the hvc/hvsi console if they have. This trips up if you use "netconsole=foo" on the command line, and has the result that you get _only_ the netconsole, because the hvc device is never added as a preferred console. Worse still if you get the netconsole configuration wrong somehow, you end up with no console at all. As it turns out we don't need to worry about checking the command line. If the user has specified "console=foo", then foo will be set as the preferred console when the command line is parsed in start_kernel(), much later than the pseries code, and so the latter setting will take effect.
