Thanks for the review.
Indeed, I may have overlooked that point. I am not sure either how much of an
issue it could be, but checking back the driver history on lore, I see that it
has already been mentioned, so let's be safe and keep a dedicated kzalloc for
vmm_table to make sure its address is safe to use with DMA.
I will send the corresponding v2.

Thanks,
Alexis
