See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-mips@vger.kernel.org swiotlb_late_init_with_default_size is an overly verbose name that doesn't even catch what the function is doing, given that the size is not just a default but the actual requested size. Rename it to swiotlb_init_late.
