commit66cee9097eupstream. Users may request that pages from an OpenCL SVM allocation be migrated to the GPU with clEnqueueSVMMigrateMem(). In Nouveau this will call into nouveau_dmem_migrate_vma() to do the migration. If the total range to be migrated exceeds SG_MAX_SINGLE_ALLOC the pages will be migrated in chunks of size SG_MAX_SINGLE_ALLOC. However a typo in updating the starting address means that only the first chunk will get migrated. Fix the calculation so that the entire range will get migrated if possible.
