Currently /proc/meminfo will not show the memory from module.

This entry "VmallocUsed: xxx" only shows the memory in the range
[VMALLOC_START, VMALLOC_END] alloced by vmalloc() ->... -> __vmalloc_node_range().

The memory which used by module is from module_alloc() -> __vmalloc_node_range().

So we will miss some memory when we calculate the total in meminfo.

Thanks,
Xishi Qiu
