In the Linux kernel, the following vulnerability has been resolved:

nouveau/firmware: use dma non-coherent allocator

Currently, enabling SG_DEBUG in the kernel will cause nouveau to hit a
BUG() on startup, when the iommu is enabled:

Fix this by using the non-coherent allocator instead, I think there
might be a better answer to this, but it involve ripping up some of
APIs using sg lists.
