spi_pcpu_stats_totalize() is a rather large macro, and is instantiated 28 times, causing a large amount of duplication in the amount of generated code. Reduce the duplication by replacing spi_pcpu_stats_totalize() by a real C function, and absorb all other common code from spi_statistics_##name##_show(). As (a) the old "field" parameter was the name of a structure member, which cannot be passed to a function, and (b) passing a pointer to the member is also not an option, due to the loop over all possible CPUs, the "field" parameter is replaced by an "offset" parameter, pointing to a location within the structure. This reduces kernel size by ca. 4 KiB (on arm32 and arm64).

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.
