I want know where Linux stores page tables. Is it in kernel virtual memory?
It seems like this has to do with virtual memory system. but I'm new to it, so if I'm in the wrong direction please let me know. And in order to answer the question myself I read some lines from a book says:
(23.2 page 8)
... Linux virtual address space consists of user portion and kernel portion...
... the kernel portion is the same across processes.
So the address space provided by kernel is in a sense a space for processes to share something? So if the page tables are put in kernel virtual memory would this mean processes can share their page tables?
