Both 4K and 64K pages are supported on powerpc. Parts of the selftest code perform alignment computations based on the PAGE_SIZE macro which is currently hardcoded to 64K for powerpc. This causes some test failures on kernels configured with 4K page size. In some cases, we need to enforce function alignment on page size. Since this can only be done at build time, 64K is used as the alignment factor as that also ensures 4K alignment.

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.
