In the current kernel, only pud huge page is supported in some architectures. P4d and pgd huge pages haven't been supported yet. And in mm/gup.c, there's no pgd huge page handling in the follow_page_mask() code path. Hence it doesn't make sense to only have gup_fast_pgd_leaf() in gup_fast code path. Here remove gup_fast_pgd_leaf() and clean up the relevant codes.

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 reStructuredText 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.
