Subject: [PATCH 0/3] dma-debug: add additional checks

Hi,

this small series of patches adds three additional checks to the dma-api
debugging code. The first one checks if dma mappings are requested for
kernel text or rodata segments.
The second check added makes noise if a device is unbound from its
driver and there are still pending dma allocations we are aware of.

Joerg
