Mauro Carvalho Chehab	9cf5116d5b	io-mapping.txt: standardize document format ... Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - Add a title for the document and for API chapter; - mark literal blocks; - Adjust whitespacing.

Keith Packard	9663f2e6a6	resources: add io-mapping functions to dynamically map large device apertures ... Impact: add new generic io_map_*() APIs Graphics devices have large PCI apertures which would consume a significant fraction of a 32-bit address space if mapped during driver initialization. Using ioremap at runtime is impractical as it is too slow. This new set of interfaces uses atomic mappings on 32-bit processors and a large static mapping on 64-bit processors to provide reasonable 32-bit performance and optimal 64-bit performance. The current implementation sits atop the io_map_atomic fixmap-based mechanism for 32-bit processors.
