Brian Welty fd0975b7cf drm/xe: Replace usage of mem_type_to_tile
Currently mem_type_to_tile() is being used to access the tile's underlying
tile.mem.vram. However, this function makes the assumption that a mem_type
will only ever map to a single tile. Now that the TTM vram manager contains
a pointer to the memory_region, make use of this in xe_bo.c.

As such, introduce a helper function res_to_mem_region() to get the
ttm_vram_mgr->vram from the BO's resource, and use this to replace usage
of mem_type_to_tile().

xe_tile is still needed to choose the migration context, so this part is
unchanged. But as this is only renaming usage, function is renamed now to
mem_type_to_migrate().

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.
