Subject: [RFC PATCH 0/5] vtime: Fix wrong user and system time accounting

Hi,

This is a proposition to fix
"[BUG nohz]: wrong user and system time accounting":
        http://lkml.kernel.org/r/20170323165512.60945ac6@redhat.com

I took Wanpeng Li's last patch and enhanced around it.

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	sched/core

HEAD: 9c7442613755e0ee0fc915ac876d88d4d2c7385e

Thanks,
	Frederic
