Like we discussed offline I think if we allow detaching and attaching kernel console from userspace we can get rid of irqsafe completely :) And in that case no need for console.idle or anything like that. Then if kernel console is attached, we can keep console uart enabled. If detached, it can do runtime PM if hardware supports it. Not sure if we need some separate new /sys entry for that, maybe we already have that with the loglevel in /proc/sys/kernel/printk?
