In addition to stream open, add xe_sync support to the OA config ioctl,
where it is even more useful. This allows e.g. Mesa to replay a workload
repeatedly on the GPU, each time with a different OA configuration, while
precisely controlling (at batch buffer granularity) the workload segment
for which a particular OA configuration is active, without introducing
stalls in the userspace pipeline.
v2: Emit OA config even when config id is same as previous, to ensure
consistent sync behavior (Jose)

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 reStructuredText 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.
