From 8b713c67bccef7cabb0ee915f47eb33d82636af9 Mon Sep 17 00:00:00 2001 From: Peter Chubb Date: Tue, 21 Aug 2007 13:51:45 +1000 Subject: [IA64] Enable early console for Ski simulator This patch cleans up the `enable early console for SKI' patch (471e7a44848f467c9b83adc3463d019d2fa8817f), and 1. potentially allows the gensparse_defconfig to work again. (there are other problems running a generic kernel on Ski) 2. fixes the `console registered twice' problem. 3. Cleans up the code by moving the `extern hpsim_cons' declaration to a new asm/hpsim.h file. Thanks to Jes for comments.
