commit 8f50af49f564d4e5 ("s390/console: Make preferred console handling
more consistent") created a separate console state for the ascii
console. This has the side effect that we register no tty for the line
mode interface as soon as there an ascii interface as default console.
Under KVM this results in no getty program on the line mode tty if the
guest has both types of interfaces.
As we can have multiple ttys at the same time we do not want to disable
the tty on sclp_line0 under KVM. So instead of checking for the console
mode, we now check for the presence of the sclp line mode interface. As
z/VM multiplexes the line mode interface on the 32xx screen we continue
to disable the line mode tty for the z/VM case.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
