Subject: [PATCH 0/5] sparc: use asm-generic/dma-mapping-common.h and pci-dma-compat.h

This patchset converts SPARC to use asm-generic/dma-mapping-common.h
and pci-dma-compat.h.

1/5, 2/5, and 3/5 converts SPARC to use
asm-generic/dma-mapping-common.h. All the preparation for this was
already merged in 2.6.31-rc1 so the chages are pretty trivial.

4/5 and 5/5 converts SPARC to use asm-generic/pci-dma-compat.h instead of 
the homegrown mechnism to handle dma_* and pci_* API.

SPARC32 has two dma_map_ops structures for pci and sbus (removing
arch/sparc/kernel/dma.c, PCI and SBUS DMA accessor). The global
'dma_ops' is set to sbus_dma_ops and get_dma_ops() returns
pci32_dma_ops for pci devices so we can use the appropriate dma
mapping operations.

The patchset is only compile-tested (sorry about it).
