Hi Konrad, Jon, This patch series contains two improvements for the SWIOTLB subsystem. The first patch adds rate-limiting to an error message, to avoid flooding the kernel log. The second patch adds a kernel command line option to aid debugging when developing support for DMA to memory outside the 32-bit address space. Thanks for your comments!
