kmap_local_page() is equivalent to kmap_atomic() except that it does not disable page faults or preemption. Where possible kmap_local_page() is preferred to kmap_atomic() - refer kernel highmem documentation. In this case, there is no need to disable page faults or preemption, so replace kmap_atomic() with kmap_local_page(), and, correspondingly, kunmap_atomic() with kunmap_local().
