The attempt to handle huge page allocations was originally added since the comments around stripping __GFP_COMP in other implementations were nonsensical, and we naively assumed that split_huge_page() could simply be called equivalently to split_page(). It turns out that this doesn't actually work correctly, so just get rid of it - there's little point going to the effort of allocating huge pages if we're only going to split them anyway.

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.
