Hello,

This patchset introduces memory shrinker for the VirtIO-GPU DRM driver
and adds memory purging and eviction support to VirtIO-GPU driver.

The new dma-buf locking convention is introduced here as well.

During OOM, the shrinker will release BOs that are marked as "not needed"
by userspace using the new madvise IOCTL, it will also evict idling BOs
to SWAP. The userspace in this case is the Mesa VirGL driver, it will mark
the cached BOs as "not needed", allowing kernel driver to release memory
of the cached shmem BOs on lowmem situations, preventing OOM kills.

The Panfrost driver is switched to use generic memory shrinker.

I think we still have some outstanding issues here - Alyssa reported some weirdness yesterday, so I just tried provoking a low-memory condition locally with this series applied and a few debug options enabled, and the results as below were... interesting.

Thanks,
Robin.
