	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!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
