This branch contains all changes that are being developed/staged in order to improve Linux kernel support in KDevelop, but are not merged upstream yet.
You will need kdevplatform (v1.7.0) and compile kdevelop from this repository by yourself (only Git versions supported for now):
http://techbase.kde.org/Projects/KDevelop4/HowToCompile
However, instead of cloning the official KDevelop repository, clone this one and checkout and compile the kernel branch. Then download, compile and install the kdev-kernel plugin:

More to come...
