Optimization is fine, but the most important thing here is to be clear
about what functional change this patch makes. As I mentioned at [1],
if this patch affects the class codes accepted, please make that clear
here.

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:
v14:- All the prerequisite reservation locking patches landed upstream,
previously were a part of this series in v13 and older
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

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.
The vmapped pages shall be pinned in memory. Previously get/put pages
were implicitly hard-pinning/unpinning the pages. This will no longer be
the case with addition of memory shrinker because pages_use_count>0 won't
determine anymore whether pages are hard-pinned (they will be soft-pinned),
while
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.

Everything that uses the mapped buffer should by agnostic to is_iomem.
The only reason for the is_iomem test 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.
