Patch 1 is for removing one division operation with multiplication.
Patch 2,3 is for clean-up related to load_balance(), there is improvement
in terms of code size and readability may be also improved.
Feel free to give a comment for this patchset.
It's tested on v3.10.
On v3.11-rc3, it can be compiled properly.
* Change from v2
[2/3]: set initial value 1 to should_balance in rebalance_domains()
as Vincent commented
[3/3]: not overwrite sum_weighted_load to represent load_per_task.
Instead, use newly load_per_task as Preeti commented
* Change from v1
Remove 2 patches, because I'm not sure they are right.
