Chris Redpath e580deb7fe HMP: Modify the runqueue stats to add a new child stat ...

The original intent here was to track unweighted runqueue load
with less resolution so we could use the least-recently-disturbed
runqueue to choose between 'closely related' load levels.

However, after experimenting with the resolution it turns out
that the following algorithm is highly beneficial for mobile
workloads.

In hmp_domain_min_load:

  * If any CPU is zero, the overall load is zero
  * If no CPUs are idle, the domain is 'fully loaded'

Additionally, the time since last migration count is used to
discriminate between idle CPUs.
