If the driver needs to use PCI configuration space to read the VPD data,
the accesses could collide with the pci_read_vpd() function.  This patch
converts the driver to use pci_read_vpd() to avoid any potential

Fix dma-api-checking warnings in Sun HME

Sun HME driver is mapping the first fragment with dma_map_single and subsequent
fragments with dma_map_page. It is unmapping all fragments with dma_unmap_single
and that produces the warning.

This patch changes it so that it unmaps only the first fragment with
dma_unmap_single and subsequent fragments are unmapped with dma_unmap_page.
