Andreas Kling 8f3f5ac8ce Kernel: Automatically populate page tables with lazy kernel regions. 
If we get an NP page fault in a process, and the fault address is in the
kernel address range (anywhere above 0xc0000000), we probably just need
to copy the page table info over from the kernel page directory.

The kernel doesn't allocate address space until it's needed, and when it
does allocate some, it only puts the info in the kernel page directory,
and any *new* page directories created from that point on. Existing page
directories need to be updated, and that's what this patch fixes.
