Yes, and understanding the intricacies of all 20+ archs boot code.
For example, I've just noticed that MIPS sets up the command line
in prom_init, called from setup_arch, so I've broken that entirely.

git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-boot-params.git

This is not going to make this merge window: I need to audit each arch
more deeply, then get help testing.

Thanks,
Rusty.
