In the Linux kernel directory, there is a file called Documentation/DMA-mapping.txt that has most of the information that you want. It will tell you what you need to know to write 64/32 bit safe drivers that are architecture independent. If you need a copy, let me know. But I suspect you have it already. Much of the same is now covered in the Rubini/Corbet "Linux Device Drivers" book (second edition only) published by O'Rielly. It has the advantage of covering lots of other relevant topics to Linux device driver writers. -- Luis F.
