mainlining shenanigans

Using the I915_MMAP_TYPE_FIXED mmap type requires the TTM backend, so for that mmap type, use __i915_gem_object_create_user() instead of i915_gem_object_create_internal(), as we really want to tests objects mmap-able by user-space. This also means that the out-of-space error happens at object creation and returns -ENXIO rather than -ENOSPC, so fix the code up to expect that on out-of-offset-space errors. Finally only use I915_MMAP_TYPE_FIXED for LMEM and SMEM for now if testing on LMEM-capable devices. For stolen LMEM, we still take the same path as for integrated, as that haven't been moved over to TTM yet, and user-space should not be able to create out of stolen LMEM anyway. v2: - Check the presence of the obj->ops->mmap_offset callback rather than hardcoding the supported mmap regions in can_mmap() (Maarten Lankhorst) Fixes: |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
