[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. cc: mingo@elte.hu Signed-off-by: Andi Kleen <ak@suse.de>
