commit280abe14b6upstream. The unused part precedes the new range spanned by the start, end parameters of vmemmap_use_new_sub_pmd(). This means it actually goes from ALIGN_DOWN(start, PMD_SIZE) up to start. Use the correct address when applying the mark using memset.

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.
