A first version of this work had been sent by Tomi Valkeinen in may 2017 

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.


changes in v3:
- rebase on top of v5.4-rc2
- Document omap_gem_new() and the new flags using the kernel-doc format

changes in v2:
- fixed build error that crept in during rebase before sending (sorry
  about that)
- rework the refcount part a bit.
