[patch V3 32/37] drm/vmgfx: Replace kmap_atomic()
There is no reason to disable pagefaults and preemption as a side effect of
kmap_atomic_prot().
Use kmap_local_page_prot() instead and document the reasoning for the
mapping usage with the given pgprot.
Remove the NULL pointer check for the map. These functions return a valid
address for valid pages and the return was bogus anyway as it would have
left preemption and pagefaults disabled.

[Spice-devel] [PATCH] Revert "drm/qxl: drop prime import/export callbacks"
...case some userspace assumes it can do cross-driver export/import
and trips over that not working. Or I do not set
DRM_PRIME_CAP_{IMPORT,EXPORT}, which breaks DRI3 ...
> I think there's qxl, virgl,
export is implemented for virgl, and import should be possible too.
qxl/bochs is simliar to vmgfx, it could be done but dma-bufs would
basically be bounce buffers (need copy from/to vram) so probably not
worth the effort.
cheers,

Yeah that's not an option.

[PATCH] Revert "drm/qxl: drop prime import/export callbacks"
This reverts commit f4c34b1e2a37d5676180901fa6ff188bcb6371f8.
Simliar to commit a0cecc23cfcb Revert "drm/virtio: drop prime
import/export callbacks". We have to do the same with qxl,
for the same reasons (it breaks DRI3).
Drop the WARN_ON_ONCE().
Fixes: f4c34b1e2a37d5676180901fa6ff188bcb6371f8
