During testing, I was generating a vmlinux binary that easily occupied more than 20MB of RAM. Since the current -kernel code loads the initrd at a fixed address behind the kernel, we were overwriting kernel data when the kernel got too big. To finally get rid of the issue, let's calculate the initrd and cmdline addresses relative to the kernel size, so we can have kernels and initrds that are as big as they want to - as long as they fit in RAM.
