Rebased/resubmitted the un-merged patches for 3.4 kernel, addressed the comments for them and re-arranged the patches sequence to be same as kernel version.

One more patch added:
http://review.whamcloud.com/#change,3745 add missing include dir

Three 3.5 support patches are also submitted for tracking purpose. I need them to start atomic_open change. They depend on Xuezhao's 3.4 patches so I didn't add any reviewer yet and I will rebase/resubmit later after Xuezhao's patches are merged.
