[PATCH 1/2] drm/virtio: fix virtio_gpu_execbuffer_ioctl locking
Lockdep says we can't call vmemdup() while having objects reserved
because it needs the mmap semaphore. So reorder the calls reserve
the objects later.

[PATCH 0/5] nouveau: unified firmware loading functions
This patchset centralizes the firmware-loading procedure to one set of functions
instead of having each engine load its firmware as it pleases. This helps ensure
that all firmware comes from the same place, namely nvidia/<chip>/.
This changes where the firmware is fetched from for falcon/xtensa/bios, but
these locations never seemed to have been official anyway. Also for most (all?)
