Since non atomic readq() and writeq() were added some of the drivers
would like to use it in a manner of:
#include <io-64-nonatomic-lo-hi.h>
...
pr_debug("Debug value of some register: %016llx\n", readq(addr));
However, lo_hi_readq() always returns __u64 data, while readq()
on x86_64 defines it as unsigned long. and thus compiler warns
about type mismatch, although they are both 64-bit on x86_64.
Convert readq() and writeq() on x86 to operate on deterministic
64-bit type. The most of architectures in the kernel already are using
either unsigned long long, or u64 type for readq() / writeq().
This change propagates consistency in that sense.
While this is not an issue per se, though if someone wants to address it,
the anchor could be the commit:

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
