dma-buf-map: Rename to iosys-map
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

drm/ttm: Add vmap/vunmap to TTM and TTM GEM helpers
The new functions ttm_bo_{vmap,vunmap}() map and unmap a TTM BO in kernel address space. The mapping's address is returned as struct dma_buf_map. Each function is a simplified version of TTM's existing kmap code. Both functions respect the memory's location ani/or writecombine flags.
On top TTM's functions, GEM TTM helpers got drm_gem_ttm_{vmap,vunmap}(), two helpers that convert a GEM object into the TTM BO and forward the call to TTM's vmap/vunmap. These helpers can be dropped into the rsp GEM object callbacks.
v5: * use size_t for storing mapping size (Christian) * ignore premapped memory areas correctly in ttm_bo_vunmap() * rebase onto latest TTM interfaces (Christian) * remove BUG() from ttm_bo_vmap() (Christian) v4: * drop ttm_kmap_obj_to_dma_buf() in favor of vmap helpers (Daniel, Christian)
