Thanks. I think it would be good to get someone who's familiar with linux/mm to take a look.
    

if you think it'll help.  I'm assuming you're targeting a different tree for 
the patch set, in which case it's probably best to keep this together with the 
rest of it.

No I think this series should be pulled by the RISC-V maintainer. The other patches in this series just refactor some code and need to be ACK'ed by their ARCH developers but I suspect the series should be pulled into RISC-V. That said since it does touch other arch should it be pulled by mm? 

BTW note that RISC-V SPARSEMEM support is pretty useful for all manner of things and not just the p2pdma discussed in the cover.
    

Thanks for porting your stuff to RISC-V!

You bet ;-)
