Subject: [PATCH -mm 0/7] transforming the PCI DMA API into the generic device model
Newsgroups: gmane.linux.kernel
Date: Friday 12th February 2010 09:33:25 UTC (over 6 years ago)
This patchset transforms the PCI DMA API into the generic device
model. It's one of the reasons why we introduced the generic DMA API
long ago; driver writers are always able to use the generic DMA API
with any bus instead of using bus specific DMA APIs such as
pci_map_single, sbus_map_single, etc (only two bus specific APIs
exist now; pci and ssb).

Some of the PCI DMA API are already implented on the top of the
generic DMA API (include/asm-generic/pci-dma-compat.h). But there are
some exceptions. This patchset finishes the transformation.
