[PATCH v20 00/10] Add generic DRM-shmem memory shrinker (part 1)

[Dmitry Osipenko <dmitry.osipenko@collabora.com>]

Hi,

This a continuation of a year-old series that adds generic DRM-shmem 
shrinker [1]. The old series became too big with too many patches, more
reasonable to split it up into multiple smaller patchsets. Here is
the firtst part that makes preparatory DRM changes.
