Unrelated to the patch, why isn't the documentation in xe_migrate.c?
Having a separate xe_migrate_doc.h with just a documentation comment
seems like a weird new pattern.

IMO the documentation should be placed either as a comment in the
relevant .c file or in an rst file under Documentation/gpu/xe.
