Jason Ekstrand e6b4678fdb anv: Move device memory maps back to anv_device_memory 
This effectively partially reverts 13fe43714c ("anv: Add helpers in
anv_allocator for mapping BOs") where we both added helpers and reworked
memory mapping to stash the maps on the BO.  The problem comes with
external memory.  Due to GEM rules, if a memory object is exported and
then imported or imported twice,  we have to deduplicate the anv_bo
struct but, according to Vulkan rules, they are separate VkDeviceMemory
objects.  This means we either need to always map whole objects and
reference-count the map or we need to handle maps separately for
separate VkDeviceMemory objects.  For now, take the later path.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library
======================================================


Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
