Greg, your stable queue has following function?
2.6.29.2 + this patch don't make correct mmap_init() on my box.
(instead, changing unrelated function)

/*

        ret = percpu_counter_init(&vm_committed_as, 0);
        VM_BUG_ON(ret);
        vm_area_cachep = kmem_cache_create("vm_area_struct",
                        sizeof(struct vm_area_struct), 0,
