Currently, only `pr_info!` (for the minimal sample) and `pr_emerg!` (for the panic handler) are there. Add the other levels as new macros, i.e. `pr_alert!`, `pr_crit!`, `pr_err!`, `pr_warn!`, `pr_notice!` and `pr_debug!`.

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.
