Mainly to be used in spinlocks etc.

+ Sensible mappings should help, discard what I wrote in the previous
commit. Nothing works unless I get vmem up and running properly.

|
+ Should start to think about how virtual memory should be handled
efficiently, I'm sort of flailing around and not actually doing
anything beneficial. The mapping system I've so far implemented
_works_, but it's not good and I'm not happy with it. I might come
back and fix/improve it, but I think I'll go ahead and do other things for
a while, might give me a better overhead view of what the virtual
memory system should do.
+ TODO: should probably document the memory layout I'm going with at the
moment.

|
+ Lots of bughunting to do, probably lots of off-by-one and so on
errors, and I make a lot of naive and possibly dangerous assumptions.
But cool start nonetheless. Should also come up with some method of
exchanging data between the init and actual kernel, probably some struct
of some sort. TODO

|
+ Will probably still need a fair bit of tweakind and documentation
improvements, but seems to work outside of the kernel. Also no valgrind
errors, which is quite promising I guess.
