That's what I assumed, however, I'm running into the same problem as
with dma-sg when I switch to vmalloc...?

I've sent a "proper" patch submission again, which has all the other
issues from the previous submission fixed. I'm hoping you can maybe have
a closer look and see if I'm doing anything subtly wrong which causes
both vmalloc and dma-sg to fail while dma-contig works.

Best, Florian
