LOL. Well I stepped in that one.

I don't have any data to support my position on this particular printk feature,
but having worked for a while on stack size reduction for a few Sony products,
I'm always a bit leery of recursive routines in the kernel. I vaguely recall
some recursive printk routines giving me problems on a product that used
a sub-4K stack configuration I did many years ago. I don't recall if it was
specifically %pV or not. Anyway YMMV.
