      dma-buf-map: Rename to iosys-map · 7938f421
      Lucas De Marchi authored
      Rename struct dma_buf_map to struct iosys_map and corresponding APIs.
      Over time dma-buf-map grew up to more functionality than the one used by
      dma-buf: in fact it's just a shim layer to abstract system memory, that
      can be accessed via regular load and store, from IO memory that needs to
      be acessed via arch helpers.
      
      The idea is to extend this API so it can fulfill other needs, internal
      to a single driver. Example: in the i915 driver it's desired to share
      the implementation for integrated graphics, which uses mostly system
      memory, with discrete graphics, which may need to access IO memory.
      
      The conversion was mostly done with the following semantic patch:
      
      	@r1@
      	@@
      	- struct dma_buf_map
      	+ struct iosys_map
      
      	@r2@
      	@@
      	(
      	- DMA_BUF_MAP_INIT_VADDR
      	+ IOSYS_MAP_INIT_VADDR
      	|
      	- dma_buf_map_set_vaddr
      	+ iosys_map_set_vaddr
      	|
      	- dma_buf_map_set_vaddr_iomem
      	+ iosys_map_set_vaddr_iomem
      	|
      	- dma_buf_map_is_equal
      	+ iosys_map_is_equal
      	|
      	- dma_buf_map_is_null
      	+ iosys_map_is_null
      	|
      	- dma_buf_map_is_set
      	+ iosys_map_is_set
      	|
      	- dma_buf_map_clear
      	+ iosys_map_clear
      	|
      	- dma_buf_map_memcpy_to
      	+ iosys_map_memcpy_to
      	|
      	- dma_buf_map_incr
      	+ iosys_map_incr
      	)
      
      	@@
      	@@
      	- #include <linux/dma-buf-map.h>
      	+ #include <linux/iosys-map.h>
      
      Then some files had their includes adjusted and some comments were
      update to remove mentions to dma-buf-map.
      
      Since this is not specific to dma-buf anymore, move the documentation to
      the "Bus-Independent Device Accesses" section.
      
      v2:
        - Squash patches
      
      v3:
        - Fix wrong removal of dma-buf.h from MAINTAINERS
        - Move documentation from dma-buf.rst to device-io.rst
      
      v4:
        - Change documentation title and level
