A first version of this work had been sent by Tomi Valkeinen in may 2017 (https://www.spinics.net/lists/dri-devel/msg140663.html). This series adds a few new OMAP_BO flags to help the userspace manage situations where it needs to use lots of buffers, and would currently run out of TILER space. The TILER space is limited to mapping 128MB at any given time and some applications might need more. This seres is also the opportunity to do some cleanup in the flags and improve the comments describing them. The user-space patches for libdrm, although ready, haven't been posted yet. It will be be done when this series have been discussed and hopefully in the process of getting merged. JJ changes in v2: - fixed build error that crept in during rebase before sending (sorry about that) - rework the refcount part a bit.
