IA64 booting is completely different. I don't think it should be in this patch. At least you would need to check with the IA64 maintainer first.
And the other thing is that this will cost memory. Either make it dependend on !CONFIG_SMALL or fix the boot code to save the command line into a kmalloc'ed buffer of the right size and __init the original one
