Subject: [PATCH 0/4] dma-debug: implement dynamic entry allocation

The HNS_ENET discussion got me thinking, why not just make DMA debug
cleverer so that (in terms of basic functionality at least) we don't
need to worry about driver- or arch-specific configuration at all?

Patches #2 and #3 are the real meat here - #1 is just some preparatory
cleanup motivated by moving printks around, and could be split out if
desired; I kept #4 separate as a possible nice-to-have depending on
what people think.

Robin.

Robin Murphy (4):
  dma-debug: Use pr_fmt()
  dma-debug: Refactor dma_debug_entry allocation
  dma-debug: Dynamically expand the dma_debug_entry pool
  dma-debug: Make leak-like behaviour apparent
