Mainly to get more forceful with stuck cpus on IA64, where the "non-maskable" interrupt is masked by local_irq_disable(). We finally get decent backtraces on stuck IA64 cpus. It took a long time to get there, KDB could not change until the base kernel could cope with INIT and recover correctly. 2006-03-22 Keith Owens <kaos@sgi.com> * Add some more xpc flags.
