global_dbcr0 has two parts, 4 bytes to save/restore the value of SPRN_DBCR0, and 4 bytes that are incremented/decremented everytime something is saving/loading the above value. This counter is only incremented/decremented, its value is never used and never read. Remove the counter and devide the size of global_dbcr0 by 2.

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.
