v2->v3:
- Simplify the code by using numerous mode only without an unfair

Could you please point me to any dependency patches I am missing?
I am getting the compilation error (latest linus tree with

Got something like below

The code will need to be compiled in either the latest linux tree as the
patches have dependency on some new memory barrier that are in 3.14.
Alternatively, you can compile with the latest tip tree.
If you have already done that, please send me your config file so that I
can reproduce the compilation error in my build environment.
Thanks,
