From c6b36e9a3c57b73c7a6bdf787baa55f21195bba9 Mon Sep 17 00:00:00 2001 From: Zachary Amsden Date: Mon, 5 Mar 2007 00:30:43 -0800 Subject: [PATCH] vmi: smp fixes Critical fixes for SMP. Fix a couple functions which needed to be __devinit and fix a bogus parameter to AP startup that just so happened to work because the low virtual mapping of memory was still established.
