From 9ba89334552b96e2127dcafb1c46ce255ecf2667 Mon Sep 17 00:00:00 2001 From: Ian Wienand Date: Wed, 21 Jun 2006 10:33:04 +1000 Subject: [IA64] SKI Simulator boot Sorry I didn't notice earlier, but that BUG_ON triggers for me on the simulator. AFAICS the mask for itv is set in cpu_init(), which comes after sal_init(). Consequently on the simulator the itv still has its start value of zero. I've probably missed something, but I wonder why at this stage of the boot you even need to save and restore the itv?
