Andreas Kling 1da0a7c949 Give each task its own page directory. ... This isn't finished but I'll commit as I go. We need to get to where context switching only needs to change CR3 and everything's ready to go. My basic idea is: - The first 4 kB is off-limits. This catches null dereferences. - Up to the 4 MB mark is identity-mapped and kernel-only. - The rest is available to everyone! While the first 4 MB is only available to the kernel, it's still mapped in every process, for convenience when entering the kernel.		2018-11-01 09:01:51 +01:00
