[PATCH v4 0/2] dma-pool fixes

[Nicolas Saenz Julienne]

Now that we have an explanation to Amir's issue, we can re-spin this
series.

---
Changes since v3:
 - Do not use memblock_start_of_DRAM()

Changes since v2:
 - Go back to v1's behavior for patch #2

Changes since v1:
 - Make cma_in_zone() more strict, GFP_KERNEL doesn't default to true
   now

 - Check if phys_addr_ok() exists prior calling it
