From: Shakeel Butt <shakeelb@xxxxxxxxxx>
Subject: kvm, mm: account shadow page tables to kmemcg
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.
[shakeelb@xxxxxxxxxx: replace (GFP_KERNEL|__GFP_ACCOUNT) with GFP_KERNEL_ACCOUNT]
