This is good enough to begin booting the Linux kernel. We do not get all the way to userspace yet; I've found two kernel bugs so far leading to immediate crashes, I suspect there are more that have crept in. At the moment we seem to get into the cpu_idle loop without managing to schedule the first kernel_thread.
Posted to begin getting comments.
