Default [Q]Upstreaming kernel from 3.4.0 to 3.4.1

I am using a Korean model of the Galaxy S4 Active(SHV-E470S). Unfortunately, this model does not have any ROMs or custom kernels, so I decided to build one myself.
The problem is, the stock kernel version of this phone is Linux 3.4.0. I searched for upstream patches, but there were no patches that upstreams a 3.4.0 kernel to 3.4.1.
Any ideas on how to upstream a 3.4.0 kernel?
