Caused by commit fa44abcad042 ("common: dma-mapping: introduce common
remapping functions") from the akpm-current tree.  I will attempt to
revert that commit today, but I may need to also revert the following 2
commits as well:

arm: use genalloc for the atomic pool
arm64: add atomic pool for non-coherent and CMA allocations

though I am not sure.  Hopefully someone will let me know in the next
few hours ...
