  at the risk of sounding self-serving, i have an online course in
beginners' linux kernel programming, for which the first several
lessons are free and should give you what you need.

http://crashcourse.ca/introduction-linux-kernel-programming/introduction-linux-kernel-programming

if you work through those first lessons and something doesn't appear
to work, let me know and i'll fix it.
