Wrap the combination of mmu->invlpg and kvm_x86_ops->tlb_flush_gva into a new function. This function also lets us specify the host PGD to invalidate and also the MMU, both of which will be useful in fixing and simplifying kvm_inject_emulated_page_fault. A nested guest's MMU however has g_context->invlpg == NULL. Instead of setting it to nonpaging_invlpg, make kvm_mmu_invalidate_gva the only entry point to mmu->invlpg and make a NULL invlpg pointer equivalent to nonpaging_invlpg, saving a retpoline.

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.
