This is the next version of the shmem backed GEM objects series
originally from Asahi, previously posted by Daniel Almeida.
One of the major changes in this patch series is a much better interface
around vmaps, which we acheive by introducing a new set of rust bindings
for iosys_map.
This patch applies to drm-rust-next with two additional commits from
drm-misc-next:
e3f4bdaf2c5b ("drm/gem/shmem: Extract drm_gem_shmem_init() from
drm_gem_shmem_create()")
c08c931060c7 ("drm/gem/shmem: Extract drm_gem_shmem_release() from
drm_gem_shmem_free()")
