    These seem to fix the original problem reporter's issue. They were run
    with 64 guests on a 32GB machine. No stability problems popped up in
    this testing, or since I last sent the patches to you. The results from
    both the test with only the first four patches and with the entire set
    of nine looked pretty identical.

    That tells me that we should only push the first four for now:

    abstract kvm x86 mmu->n_free_mmu_pages
    rename x86 kvm->arch.n_alloc_mmu_pages
    replace x86 kvm n_free_mmu_pages with n_used_mmu_pages
    create aggregate kvm_total_used_mmu_pages value

    -- Dave
