Open code the call to mmu->translate_gpa() when loading nested PDPTRs and kill off the existing helper, kvm_read_guest_page_mmu(), to discourage incorrect use. Reading guest memory straight from an L2 GPA is extremely rare (as evidenced by the lack of users), as very few constructs in x86 specify physical addresses, even fewer are virtualized by KVM, and even fewer yet require emulation of L2 by L0 KVM. No functional change intended.

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.
