Hii Christoph,
	I nearly forgot about this, and now I would like to complete
this task.
However, even after two months I am still a newbie and there are a few
questions that I would like to ask :

1.	Multiple files will be affected by this change, who do you think 
	I should send my patches to ??
2.	Should I send my patches as a patchset of multiple small patches
	chaging a particular API for e.g. sending all patches that change
	pci_map_single() to dma_map_single() in one file in the same patchset ??
3.	I literally have little idea on how to change the comments and
	docs which refer to these APIs.
4.	And what if a maintainer likes the previous APIs for simplicity
	and rejects the patches that try to change them ??

Thanks,

Suraj Upadhyay.
