Gunnar Beutner b5aad1c81d Kernel: Fix GDT and segment selectors to make userland work on x86_64 
Userland faulted on the very first instruction before because the
PML4T/PDPT/etc. weren't marked as user-accessible. For some reason
x86 doesn't care about that.

Also, we need to provide an appropriate userspace stack segment
selector to iretq.
