This was pointed out by Ville and Pekka in their replies, but
forgot to apply the change properly before pushing. Sorry for
the noise!

Hi list,
After several days of trying I realize my too small/old brain is unable
to map around how to assign/connect a panel to the mipi_dsi-node in a
device.
We are using a 'tdo,tl070wsh30' panel connected to the
mipi-dsi-interface of a imx8mm.

Set allow_cache_hints to 1 for the vb2_queue capture queue in the
STM32MP15xx DCMI V4L2 driver. This allows us to allocate buffers
with the V4L2_MEMORY_FLAG_NON_COHERENT set. On STM32MP15xx SoCs,
this enables caching for this memory, which improves performance
when being read from CPU.

This series:
1. Adds common drm-shmem memory shrinker
2. Enables shrinker for VirtIO-GPU driver
3. Switches Panfrost driver to the common shrinker
Changelog:
v12:- Fixed the "no previous prototype for function" warning reported by
kernel build bot for v11.
- Fixed the missing re
Replace all drm-shmem locks with a GEM reservation lock. This makes locks
consistent with dma-buf locking convention where importers are responsible
for holding reservation lock for all operations performed over dma-bufs,
preventing deadlock between dma-buf importers and exporters.

The vmapped pages shall be pinned in memory. Previously get/put pages were
implicitly pinning/unpinning the pages. This will no longer be the case
with addition of memory shrinker because pages_use_count>0 won't determine
whether pages are pinned anymore, while the new pages_pin_count will do
that.
Factor out pages allocation from drm_gem_shmem_get_pages() into
drm_gem_shmem_acquire_pages() function and similar for the put_pages()
in a preparation for addition of shrinker support to drm-shmem.
Once shrinker will be added, the pages_use_count>0 will no longer determine
whether pages are pinne
Factor out pages unpinning code from drm_gem_shmem_purge() into new
drm_gem_shmem_unpin_pages(). This prepares code for addition of memory
shrinker support. The new common function will be used by shrinker for
eviction of shmem pages.

And new pages_pin_count field to struct drm_gem_shmem_object that will
determine whether pages are evictable by memory shrinker. The pages will
be evictable only when pages_pin_count=0. This patch prepares code for
addition of the memory shrinker that will utilize the new field.

Introduce common drm-shmem shrinker for DRM drivers.
To start using drm-shmem shrinker drivers should do the following:
1. Implement evict() callback of GEM object where driver should check
whether object is purgeable or evictable using drm-shmem helpers and
perform the shrinking action
2.
Everything that uses the mapped buffer should by agnostic to is_iomem.
The only reason for the is_iomem test is is that we're setting shmem->vaddr
to the returned map->vaddr. Now that the shmem->vaddr code is gone, remove
the obsoleted is_iomem test to clean up the code.
