This reverts commit 1791ebd131.
setup_kup() was inlined to manage conflict between PPC32 marking
setup_{kuap/kuep}() __init and PPC64 not marking them __init.
But in fact PPC32 has removed the __init mark for all but 8xx
in order to properly handle SMP.
In order to make setup_kup() grow a bit, revert the commit
mentioned above but remove __init for 8xx as well so that
we don't have to mark setup_kup() as __ref.
Also switch the order so that KUAP is initialised before KUEP
because on the 40x, KUEP will depend on the activation of KUAP.

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.
