This kernel is EOL and not supported anymore. If you want some bugfixes, please implement them by yourself. All sources are available on my Github. Please download the sources for i9300 and apply the defconfig for the Note 2 instead of the one for i9300 to compile my Note 2 kernel. Bugfixes and other changes to the code is something you have to do by yourself, because I can't support this kernel anymore since I don't own a Note 2 anymore.
