Peter Wemm f1009e1e1f Commit Doug White and Alan Cox's fix for the cross-ipi smp deadlock. ... We were obtaining different spin mutexes (which disable interrupts after aquisition) and spin waiting for delivery. For example, KSE processes do LDT operations which use smp_rendezvous, while other parts of the system are doing things like tlb shootdowns with a different mutex. This patch uses the common smp_rendezvous mutex for all MD home-grown IPIs that spinwait for delivery. Having the single mutex means that the spinloop to aquire it will enable interrupts periodically, thus avoiding the cross-ipi deadlock.
