Hi Hans,
I apologize for the delay in answering, but I was on vacation.
Thank you to have pointed out the compilation problem below.
I've corrected it (unsigned long is now used for dma_attrs).
I've still have few points to fix, and I will propose a new set of patches
beginning of next week.
Regards,
Jean-Christophe.
