This change is required to make the system respond faster to any
realtime events (sending or receiving data packets).
It will wake up at least one core 1000 times a second which will result
in finer timer granularity and make scheduling smoother. HTB for
example sends large packet bursts on each timer even to keep up data
rates which is not helpful for most applications.
The change might increase resource consumption and overhead slightly on
some systems, but since we are running in an idle-dyntick configuration,
we should not keep awake any cores that have not been awake before.

This feature is now disabled (was disabled on ARM before) as we do not
need it:
"Select this option to enable fine granularity task irq time accounting.
This is done by reading a timestamp on each transitions between softirq
and hardirq state, so there can be a small performance impact."

This is a new type of metric to find out what resource is currently a
bottleneck for the whole system. We might use this for graphs.

This is not necessary on our systems and according to the documentation
will reduce code size of the allocator which will result in better
performance.

Hello,
This patchset is unfortunately incomplete due to the rate limiting on our mailserver.
I will submit it again as soon as that is being fixed.
