this is my first post to this forum.
Question is Where should i ask about Android kernel?

Example:- 1. When i make Android-kernel by command
make --warn-undefined-variables -d -p uImage
Then i got lots of warning: undefined variable.
As i search about it on web i got following link which i cant post here due to restrictions of this forum.

I tried to understand But confuse about it.

Like this lots of questions about Android-kernel.
