Subject: [UPDATE PATCH 04/19] drivers/scsi/ahci: Use the DMA_{64, 32}BIT_MASK constants
Date: Sun, 20 Mar 2005 13:37:47 +0100 [thread overview]
Message-ID: <20050320123747.GD3491@localhost.localdomain> (raw)
In-Reply-To: <20050220165530.GD14375@helium.tklauser.home>
The previous patch did not compile cleanly on all architectures so
here's a fixed one.
Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()
This patch includes 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
