enter_svm_guest_mode() first calls nested_vmcb02_prepare_control() to copy
control fields from VMCB12 to the current VMCB, then
nested_vmcb02_prepare_save() to perform a similar copy of the save area.
This means that nested_vmcb02_prepare_control() still runs with the
previous save area values in the current VMCB so it shouldn't take the L2
guest CS.Base from this area.
Explicitly pull CS.Base from the actual VMCB12 instead in
enter_svm_guest_mode().
Granted, having a non-zero CS.Base is a very rare thing (and even
impossible in 64-bit mode), having it change between nested VMRUNs is
probably even rarer, but if it happens it would create a really subtle bug
so it's better to fix it upfront.

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.
