Subject: [PATCH] rename per CPU init_cfs_rq to init_tg_cfs_rq

Hi Folks:

I am going through the task scheduling code and something looks strange.
A per cpu variable shares the same name with a function. This is
potentially confusing. Not sure if you guys have noticed it but here's
another cleanup patch to address the issue.

Cheers,

Ani
