Extracted from a larger queue that fixes kcpustat on nohz_full, these two patches have value on their own as they remove two write barriers on nohz_full context switch.
Frederic Weisbecker (2): vtime: Rename vtime_account_system() to vtime_account_kernel() vtime: Spare a seqcount lock/unlock cycle on context switch
