Jesse Gross, would you like to pick it up to your tree?

Lots of network drivers use u64_stats_sync infrastructure for statistics
on 32bit or 64bit hosts no matte
From: Shan Wei
no change vs v1.
Lots of drivers use this kind to read/write per-cpu variable.
stats = this_cpu_ptr(dp->stats_percpu);
u64_stats_update_begin(&stats->sync);
stats->tx_packets++;
u64_stats_update_begin(&stats->sync);
