improve kernel/hrtimers.c locking: use a per-CPU base with a lock to
control locking of all clocks belonging to a CPU. This simplifies
code that needs to lock all clocks at once. This makes life easier
for high-res timers and dyntick. No functional change should happen
due to this.

..

-struct hrtimer_base;
+struct hrtimer_clock_base;

It is better to place these forward declarations right at the top of the
include file. That prevents people from later accidentally adding another
forward declaration of the same structure at an earlier point in the file,
and keeps all the same types of thing in the same place.

(two instances in this file)

+ * struct hrtimer_cpu_base - the per cpu clock bases
+ * @lock: lock protecting the base and associated clock bases and timers

Looks crappy in 80-cols. But I don't know if breaking this line will break
kerneldoc?
