Aharon Landau b79f2dc5ff RDMA/umem: Avoid undefined behavior of rounddown_pow_of_two() ... rounddown_pow_of_two() is undefined when the input is 0. Therefore we need to avoid it in ib_umem_find_best_pgsz and return 0. Otherwise, it could result in not rejecting an invalid page size which eventually causes a kernel oops due to the logical inconsistency.
