Peter Zijlstra (Intel) 166d6008fa timers/nohz: Update NOHZ load in remote tick
[ Upstream commit ebc0f83c78a2d26384401ecf2d2fa48063c0ee27 ]

The way loadavg is tracked during nohz only pays attention to the load
upon entering nohz.  This can be particularly noticeable if full nohz is
entered while non-idle, and then the cpu goes idle and stays that way for
a long time.

Use the remote tick to ensure that full nohz cpus report their deltas
within a reasonable time.

[ swood: Added changelog and removed recheck of stopped tick. ]
