From: Zachary Amsden Date: Mon, 5 Mar 2007 08:30:43 +0000 (-0800) Subject: [PATCH] vmi: smp fixes X-Git-Tag: v2.6.21-rc3~73 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=c6b36e9a3c57b73c7a6bdf787baa55f21195bba9;p=linux-2.6-omap-h63xx.git [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.
