Last time I think I used v4.13 in the same environment and I think it worked
fine, most probably because renesas_sdhi_internal_dmac wasn't there, yet ;)
I checked renesas-drivers-2017-10-03-v4.14-rc3 if there is anything newer
regarding drivers/mmc/host/renesas_sdhi_internal_dmac.c but doesn't look so.
Any idea what I missed?
How much swiotlb memory do you have? The default is 64 MiB:
software IO TLB [mem 0x77fff000-0x7bfff000] (64MB) mapped at
[ffffffc037fff000-ffffffc03bffefff]
Same here:
software IO TLB [mem 0x4ffff000-0x53fff000] (64MB) mapped at
[ffff80000ffff000-ffff800013ffefff]
Then, who else is consuming lots of swiotlb memory?
Hmm, any idea how to find that?
The dmesg doesn't seem to have more infos about that (?)

Ugh, and the mapping failure isn't even handled correctly...
:(
