[PATCH] drm/bochs: fix bochs_gem_prime_mmap
ttm_fbdev_mmap() just doesn't work. It appears to work fine, mmap()
returns success, but any attempt to actually access the mapping causes a
SIGBUS.
We can just use drm_gem_prime_mmap() instead. Almost. We have to copy
over the start offset from the ttm_buffer_object vm_node to the
drm_gem_object vm_node so the offset math in drm_gem_prime_mmap() works
correctly for us even though we use ttm to manage our objects.

[PATCH 1/3] drm/virtio: implement prime mmap
Sync gem vm_node.start with ttm vm_node.start,
then we can just call drm_gem_prime_mmap().

[PATCH 19/20] drm/xlnx: Initialize DRM driver instance with CMA helper macro
...RIVER_OPS_VMAP_WITH_DUMB_CREATE(zynqmp_dpsub_dumb_create),
The only effective change here is
- .gem_prime_import_sg_table = drm_gem_cma_prime_import_sg_table,
- .gem_prime_mmap = drm_gem_cma_prime_mmap,
+ .gem_prime_import_sg_table = drm_gem_cma_prime_import_sg_table_vmap,
+ .gem_prime_mmap = drm_gem_prime_mmap,
The change is significant, and I have a hard time following the code to
verify that it's correct, or if it's an undesired side effect. If it's
correct, could the change be mentioned in the commit message, with at
least a brief explanation of why this is correct, and what the
