[PATCH] Remove need for early lockdep init
I think it was only needed for the printks and we can do them later.
I put in a single early_printk so that we know the kernel is alive
(early_printk doesn't need any locks)
This makes some things easier for initialization of unwind for
lockdep, which is needed by later patches.
