Mark Johnston 55e020a6f9 amd64: Reduce the amount of cpuset copying done for TLB shootdowns ... We use pmap_invalidate_cpu_mask() to get the set of active CPUs. This (32-byte) set is copied by value through multiple frames until we get to smp_targeted_tlb_shootdown(), where it is copied yet again. Avoid this copying by having smp_targeted_tlb_shootdown() make a local copy of the active CPUs for the pmap, and drop the cpuset parameter, simplifying callers. Also leverage the use of the non-destructive CPU_FOREACH_ISSET to avoid unneeded copying within smp_targeted_tlb_shootdown().
