The scmi_common_fastchannel_db_ring() function calls either ioread64()
or ioread64_hi_lo() depending on whether it is compiler for 32-bit
or 64-bit architectures.
The same logic is used to define ioread64() itself in the
linux/io-64-nonatomic-hi-lo.h header file, so the special case
is not really needed.
The behavior here should not change at all.

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 reStructuredText 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.
