Today we added some logging infrastructure. This logger uses a circular buffer that can be safely written to from an interrupt context. The logger supports different levels that can be adjusted at a per module basis. It also only allocates when necessary, which means that we should be able to construct some logs before the allocator even comes up

1:34:54 Oops... spinlocks aren't right
2:01:45 It works!
