Code has been converted over to the new explicit on-stack plugging,
and delay users have been converted to use the new API for that.

- It looks incorrect to use blk_rq_map_sg with pci_map_page here about
DMA mappings. dma_map_sg?- better to use dma_map_page instead of pci_map_page.

Move DMA-mapping.txt to Documentation/PCI/.
DMA-mapping.txt was supposed to be moved from Documentation/ to

were updated, along with a few other text files, but the file
itself somehow escaped being moved, so move it and update more
text files and source files with its new location.Signed-off-by: Randy Dunlap
