Yes. Kernel works on static adress space.

I'm not sure if you want to understand "how kernel manages memory for
its internal DS". If its the case you should read the following
documents.

1) Read the chapter 8 of Linux Device driver 3rd edition.

http://lwn.net/Kernel/LDD3/

2) To understand slab allocator read the following papers by bonwick

   a) 94 paper describing slab allocator:

   b) Its followup in 2001
   
   http://static.usenix.org/event/usenix01/full_papers/bonwick/bonwick_html/index.html

3) These should be enough. But if you want to know detailed architecture
of how virtual memory manager work you should read Gorman's book on
Linux virtual memory manager. Its a free pdf. can be found here:

Happy hacking.
