hugetlb_no_page() and hugetlb_wp() call anon_vma_prepare(). In preparation for hugetlb to safely handle faults under the VMA lock, use vmf_anon_prepare() here instead. Additionally, passing hugetlb_wp() the vm_fault struct from hugetlb_fault() works toward cleaning up the hugetlb code and function stack.

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.
