Here's updated version the fourth and the last bunch of of patches that brings
initial 5-level paging enabling.
Please review and consider applying.
The situation with assembly hasn't changed much. I still not see a way to get
it work.
In this version I've included patch to fix comment in return_from_SYSCALL_64,
fixed bug in coverting startup_64 to C and updated the patch which allows to
opt-in full address space.
