From bca50fc025636b481a3a1a2b95a1634955d1eb62 Mon Sep 17 00:00:00 2001
From: Russell King <rmk@arm.linux.org.uk>

Subject: Add drm_armada_cache_reap()

Provide an API to allow libdrm-armada's internal BO cache to be reaped.
This API returns TRUE if there are still BOs in the cache which may be
reaped at a later time, which allows users to schedule further reaps.
