[microblaze-uclinux] 2.6.30-rc4: missing PCI_DMA_BUS_IS_PHYS

["Steve Magnani" <steve@xxxxxxxxxxxxxxx>]

Michal,

I'm working on porting the mainline kernel into our environment and ran 
across the following compile error:

drivers/scsi/scsi_lib.c: In function `scsi_calculate_bounce_limit':
drivers/scsi/scsi_lib.c:1626: error: `PCI_DMA_BUS_IS_PHYS' undeclared 
(first use in this function)

Based on what I see in other architectures I think arch/microblaze/
include/asm/pci.h needs something like this added:

/* The PCI address space does equal the physical memory
 * address space (no IOMMU).  The IDE and SCSI device layers use
 * this boolean for bounce buffer decisions.
 */
#define PCI_DMA_BUS_IS_PHYS     (1)


Regards,
