[Greg KH]

ChangeSet 1.1500.11.5, 2004/02/02 11:05:17-08:00, dsaxena@xxxxxxxxxxx

[PATCH] PCI: Replace pci_pool with generic dma_pool, part 2

include/linux changes:

- Add dma_pools member to struct device
- Add include/linux/dmapool.h
- Remove pools memober from struct pci_dev
- Replace pci_pool_* functions with macros that map to dma_pool_* functions
