commit d97e5e6160 upstream.
The size of kvm's shadow page tables corresponds to the size of the
guest virtual machines on the system. Large VMs can spend a significant
amount of memory as shadow page tables which can not be left as system
memory overhead. So, account shadow page tables to the kmemcg.

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.
