Andrey Grodzovsky c97f082c13 drm/ttm: Clear all DMA mappings on demand
Used by drivers supporting hot unplug to handle all
DMA IOMMU group related dependencies before the group
is removed during device removal and we try to access
it after free when last device pointer from user space
is dropped.

v3:
Switch to ttm_bo_get_unless_zerom
Iterate bdev for pinned list
Switch to ttm_tt_unpopulate

README

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.
