This is a really useful function, but it's buried in the copy_ccw_from_iova() routine so that ccwchain_calc_length() can just work with Format-1 CCWs while doing its counting. But it means we're translating a full 2K of "CCWs" to Format-1, when in reality there's probably far fewer in that space. Let's factor it out, so maybe we can do something with it later.

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.
