This adds a function to dump the DMA mappings that the debugging code is
aware of -- either for a single device, or for _all_ devices.

This can be useful for debugging -- sticking a call to it in the DMA
page fault handler, for example, to see if the faulting address _should_
be mapped or not, and hence work out whether it's IOMMU bugs we're
seeing, or driver bugs.

Patch from SAN People

Following changes were made to clock.c:

1) Replaced <asm/hardware/clock.h> with <linux/clk.h>
2) Removed old unused clk_enable & clk_disable.
3) Replaced clk_use/clk_unuse with clk_enable/clk_disable.

Otherwise it's the same as the previous patch.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
