Compiling linux kernel with modified source

How can I compile a kernel with modified source using bitbake?

Hi

For small changes you would probably want to create patches for your changes and apply them with a *.bbappend to our existing kernel recipes.
For bigger changes you would probably bbappend to change the SRC_URI and SRCREF to point to a revision on your own git server.
