Since the current implementation of VMCS12 does a memcpy in and out of guest memory, we do not need current_vmcs12 and current_vmcs12_page anymore. current_vmptr is enough to read and write the VMCS12. And David Matlack noted: This patch also fixes dirty tracking (memslot->dirty_bitmap) of the VMCS12 page by using kvm_write_guest. nested_release_page() only marks the struct page dirty.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
