alloc_xenballooned_pages() and free_xenballooned_pages() are used as direct replacements of xen_alloc_unpopulated_pages() and xen_free_unpopulated_pages() in case CONFIG_XEN_UNPOPULATED_ALLOC isn't defined. Guard both functions with !CONFIG_XEN_UNPOPULATED_ALLOC and rename them to the xen_*() variants they are replacing. This allows to remove some ifdeffery from the xen.h header file. Adapt the prototype of the functions to match.

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.
