The size limit macros are located further down in printk.c and behind ifdef conditionals. This complicates their usage for upcoming changes. Move the macros into internal.h so that they are still invisible outside of printk, but easily accessible for printk. Also, the maximum size of formatted extended messages does not need to be known by any code outside of printk, so move it to internal.h as well. And like CONSOLE_LOG_MAX, for !CONFIG_PRINTK set CONSOLE_EXT_LOG_MAX to 0 to reduce the static memory footprint.

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 Restructured Text 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.
