[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?
