Commitaa88b68c3b("thp: keep huge zero page pinned until tlb flush") introduced tlb_remove_page() for huge zero page to keep it pinned until flush is complete and prevents the page from being split under us. But huge zero page is kept pinned until all relevant mm_users reach zero since the commit6fcb52a56f("thp: reduce usage of huge zero page's atomic counter"). So tlb_remove_page_size() for huge zero pmd is unnecessary now.

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.
