I am still not sure about this. With current upstream we get

 PCI: Probing PCI hardware                                     
 PCI: Probing PCI hardware done                                                                                                                       
 HugeTLB: unsupported default_hugepagesz 2097152. Reverting to 16777216                                                                               
 HugeTLB registered 16.0 MiB page size, pre-allocated 0 pages                                                                                         
 HugeTLB registered 16.0 GiB page size, pre-allocated 0 pages  

That warning is added by

d715cf804a0318e83c75c0a7abd1a4b9ce13e8da

Which should be good enough right ?
