drm/gud: Enable synchronous flushing by default
gud has a module parameter that controls whether framebuffer flushing happens synchronously during the commit or asynchronously in a worker.
GNOME before version 3.38 handled all displays in the same rendering loop. This lead to gud slowing down the refresh rate for a faster monitor. This has now been fixed so lets change the default.
The plan is to remove async flushing in the future. The code is now structured in a way that makes it easy to do this.

drm/gud: Don't retry a failed framebuffer flush
If a framebuffer flush fails the driver will do one retry by requeing the worker. Currently the worker is used even for synchronous flushing, but a later patch will inline it, so this needs to change. Thinking about how to solve this I came to the conclusion that this retry mechanism was a fix for a problem that was only in the mind of the developer (me) and not something that solved a real problem.
So let's remove this for now and revisit later should it become necessary. gud_add_damage() has now only one caller so it can be inlined.

The source of this warning is in iosys_map_clear() called from dma_buf_vmap(). It conditionally sets values based on map->is_iomem. The iosys_map variables are allocated uninitialized on the stack leading to ->is_iomem having all kinds of values and not only 0/1.
Fix this by zeroing the iosys_map variables.

drm/gud: Fix endianness in gud_xrgb8888_to_color() helper
DRM formats are defined to be little-endian, unless the DRM_FORMAT_BIG_ENDIAN flag is set. Hence when converting from one format to another, multi-byte pixel values loaded from memory must be converted from little-endian to host-endian. Conversely, multi-byte pixel values written to memory must be converted from host-endian to little-endian. Currently only drm_fb_xrgb8888_to_rgb332_line() includes endianness handling.
Fix gud_xrgb8888_to_color() on big-endian platforms by adding the missing endianness handling.

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/format-helper: Rework format-helper conversion functions
Move destination-buffer clipping from all format-helper conversion functions into callers. Support destination-buffer pitch. Only distinguish between system and I/O memory, but use same logic everywhere.
Simply harmonize the interface and semantics of the existing code. Not all conversion helpers support all combinations of parameters. We have to add additional features when we need them.

The newly returned values point to the first byite of the data stored in the framebuffer BOs. Drivers that access the BO data should use it.

Abstract the framebuffer details by mapping its BOs with a call to drm_gem_fb_vmap(). Unmap with drm_gem_fb_vunmap().
The call to drm_gem_fb_vmap() ensures that all BOs are mapped correctly. Gud still only supports single-plane formats.
No functional changes.
