Replace the calls to ttm_eu_reserve_buffers() by using the drm_exec helper instead. Also make sure the locking loop covers any calls to xe_bo_validate() / ttm_bo_validate() so that these function calls may easily benefit from being called from within an unsealed locking transaction and may thus perform blocking dma_resv locks in the future. For the unlock we remove an assert that the vm->rebind_list is empty when locks are released. Since if the error path is hit with a partly locked list, that assert may no longer hold true we chose to remove it. v3: - Don't accept duplicate bo locks in the rebind worker. v5: - Loop over drm_exec objects in reverse when unlocking. v6: - We can't keep the WW ticket when retrying validation on OOM. Fix.

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.
