Konstantin Belousov 83c001d3c2 Re-apply r306516 (by cem): ... Reduce the cost of TLB invalidation on x86 by using per-CPU completion flags Reduce contention during TLB invalidation operations by using a per-CPU completion flag, rather than a single atomically-updated variable. On a Westmere system (2 sockets x 4 cores x 1 threads), dtrace measurements show that smp_tlb_shootdown is about 50% faster with this patch; observations with VTune show that the percentage of time spent in invlrng_single_page on an interrupt (actually doing invalidation, rather than synchronization) increases from 31% with the old mechanism to 71% with the new one. (Running a basic file server workload.)
