[RFC PATCH 5/5] drm/etnaviv: account memory used by GEM buffers

[Lucas Stach <l.stach@pengutronix.de>]

Etnaviv GEM buffers are pinned into memory as soon as we allocate
the pages backing the object and only disappear when freeing the
GEM object as there is no shrinker hooked up for unused buffers.
