Because the allmodconfig logic just sets every symbol to M or Y, it has the effect of always generating a 64-bit config, because CONFIG_PPC64 becomes Y. So to make it easier for folks to test 32-bit code, provide a phony defconfig target that generates a 32-bit allmodconfig. The 32-bit port has several mutually exclusive CPU types, we choose the Book3S variants as that's what the help text in Kconfig says is most common.

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.
