Subject[PATCH] rcu: Report a quiescent state of TASKS_RCU on a tick from user

Hello Paul,

You removed the reporing while simplifying the commit 508880df6 :)
Fold this patch onto the commit or add, whatever you want.

Thanks,

Subject: [PATCH] rcu: Report a quiescent state of TASKS_RCU on a tick from
user

The reporting was removed while simplifying the commit 508880df6 (rcu:
Improve rcu_note_voluntary_context_switch() reporting). Add it back.
