printk: nbcon: Init @nbcon_seq to highest possible
When initializing an nbcon console, have nbcon_alloc() set @nbcon_seq to the highest possible sequence number. For all practical purposes, this will guarantee that the console will have nothing to print until later when @nbcon_seq is set to the proper initial printing value. This will be particularly important once kthread printing is introduced because nbcon_alloc() can create/start the kthread before the desired initial sequence number is known.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. 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.
