Huang Ying 184e1fdfea x86, mce: fix a race condition about mce_callin and no_way_out ... If one CPU has no_way_out == 1, all other CPUs should have no_way_out == 1. But despite global_nwo is read after mce_callin, global_nwo is updated after mce_callin too. So it is possible that some CPU read global_nwo before some other CPU update global_nwo, so that no_way_out == 1 for some CPU, while no_way_out == 0 for some other CPU. This patch fixes this race condition via moving mce_callin updating after global_nwo updating, with a smp_wmb in between. A smp_rmb is added between their reading too.
