Merge branch 'akpm' (patches from Andrew) 

Merge final patch-bomb from Andrew Morton:
 "Various leftovers, mainly Christoph's pci_dma_supported() removals"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  pci: remove pci_dma_supported
  usbnet: remove ifdefed out call to dma_supported
  kaweth: remove ifdefed out call to dma_supported
  sfc: don't call dma_supported
  nouveau: don't call pci_dma_supported
  netup_unidvb: use pci_set_dma_mask insted of pci_dma_supported
  cx23885: use pci_set_dma_mask insted of pci_dma_supported
  cx25821: use pci_set_dma_mask insted of pci_dma_supported
  cx88: use pci_set_dma_mask insted of pci_dma_supported
  saa7134: use pci_set_dma_mask insted of pci_dma_supported
  saa7164: use pci_set_dma_mask insted of pci_dma_supported
  tw68-core: use pci_set_dma_mask insted of pci_dma_supported
  pcnet32: use pci_set_dma_mask insted of pci_dma_supported
  lib/string.c: add ULL suffix to the constant definition
  hugetlb: trivial comment fix
  selftests/mlock2: add ULL suffix to 64-bit constants
  selftests/mlock2: add missing #define _GNU_SOURCE
