From: Ilia Mirkin <imirkin@xxxxxxxxxxxx> commit bd6e07e72f37f34535bec7eebc807e5fcfe37b43 upstream. The struct is giant, and triggers an order-7 allocation (512K). There is no reason for this to be kmalloc-type memory, so switch to vmalloc. This should help loading nouveau on low-memory and/or long-running systems. Reported-by: Nathan E.
