I have not a chance to run a bisection yet, but I suspect this is coming
from Christoph's latest batch of DMA-API changes in ARM64 under the
merge commit befa93633193e5327e4045d1e5fa29114580fa5d ("Merge tag
'dma-mapping-4.20-1' of git://git.infradead.org/users/hch/dma-mapping"),

I guess Catalin can pick this up for -rc1, since there's also the kprobes
RO fix kicking around for arm64?

I can pick it up at -rc1 as I don't have Christoph's patches in my tree
(and don't want to base a branch on some random point in the merging
window).

Alternatively, it could go via Christoph's tree for -rc1.

I'll send it on tomorrow.
