[ Upstream commit 43cf0e05089afe23dac74fa6e1e109d49f2903c4 ] The events hugepage_set_pmd, hugepage_set_pud, hugepage_update_pmd and hugepage_update_pud are only called when CONFIG_PPC_BOOK3S_64 is defined. As each event can take up to 5K regardless if they are used or not, it's best not to define them when they are not used. Add #ifdef around these events when they are not used.

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.
