There is a set of functions and symbols related to performing "tag_process" immediate commands to clear the IPA pipeline. The name is related to one of the commands issued when doing this, but it doesn't really convey the overall purpose of taking this action. The purpose is to take some steps to "clear out" the hardware pipeline, and to wait until that process completes, to ensure the IPA hardware is in a well-defined state. Rename these symbols to use "pipeline_clear" in their names instead. Add some comments to explain a bit more about what's going on.

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.
