ok, fine, I'll do it now.

Just saying in case it's an issue - I was looking at 
http://git.infradead.org/users/hch/dma-mapping.git/log/refs/heads/for-next 
and the order is not the same as this series and would cause an 
intermediate build breakage at 9f5ec52ae501 ("scsi: scsi_transport_sas: 
cap shost opt_sectors according to DMA optimal limit")

Cheers,
