Is the /mm directory the correct place to look? It seems to contain memory related code but from what little I have read it seems at a higher level building in some cases at least on kmalloc. I am just curious about a point raised by the SVA dissertation(by John Criswell). Another point he does

Hi, Where do I find the code in the kernel related to the MMU and resolving memory addresses? I am trying to understand what the implications are if code like this has bugs and the impact on the various functions that return chunks of memory for use via pointers (either as pages or kmalloc
