[patch 11/12] drivers/block/umem.c: Use the DMA_{64, 32}BIT_MASK constants

[domen]

From: Tobias Klauser <tklauser@xxxxxxxxxxx>



Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()
These patches include dma-mapping.h explicitly because it caused errors
on some architectures otherwise.
See http://marc.theaimsgroup.com/?t=108001993000001&r=1&w=2 for details
