This is useful in the next patch, to keep a saved copy of vmcb12 registers and pass it around more easily. Instead of blindly copying everything, we just copy EFER, CR0, CR3, CR4, DR6 and DR7 which are needed by the VMRUN checks. If more fields will need to be checked, it will be quite obvious to see that they must be added in struct vmcb_save_area_cached and in nested_copy_vmcb_save_to_cache(). __nested_copy_vmcb_save_to_cache() takes a vmcb_save_area_cached parameter, which is useful in order to save the state to a local variable.

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.
