FNAME(invlpg)() and kvm_mmu_invalidate_gva() take a gva_t, i.e. unsigned long, as the type of the address to invalidate. On 32-bit kernels, the upper 32 bits of the GPA will get dropped when an L2 GPA address is invalidated in the shadowed nested TDP MMU. Convert it to u64 to fix the problem.

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.
