Hi Petr,

The problem is that CONFIG_SRCU is not selected. This must be selected
by any modules that requires SRCU. However, printk.c is _always_ built
into the kernel (even if !CONFIG_PRINTK). The registration of consoles
and the console list (which uses SRCU) is _always_ built into the
kernel.

So should CONFIG_SRCU now always be active?

@paulmck: Do you have a problem with permanently activating CONFIG_SRCU?
