In particular: - smp_tlb_mtx is no longer used, so it is axed. - smp rendezvous lock isn't really a leaf spin-mutex. Its bad placement in the table, however, has been the source of a false positive LOR reporting with the dt_lock. However, smp rendezvous lock would have had sched_lock there for older lock, so it wasn't still a leaf lock. - allpmaps is only used in ia32 architecture, so it is inserted in the appropriate stub. Addictionally: - kse_zombie_lock is no longer present, so its definition is axed out. - zombie_lock doesn't need to have an exported symbol, so just let's it be declared as static.
