It's horrid and if we inline it into callers, we can get rid of a lot of sugar around. So: * x_char handling becomes a single iowrite8. * xmit->buf handling is a single loop simply writing characters one by one directly from the buf instead of complex cnt_to_end computations. Until the buf is empty or fifo size is reached.

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.
