Linux kernel source tree

We need to flush render caches before fence signalling, where we might release the memory for reuse. We can't rely on userspace doing this, so flush render caches after the batch, but before user fence- and dma_fence signalling. Copy the cache flush from i915, but omit PIPE_CONTROL_FLUSH_L3, since it should be implied by the other flushes. Also omit PIPE_CONTROL_TLB_INVALIDATE since there should be no apparent need to invalidate TLB after batch completion. v2: - Update Makefile for OOB WA.

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.
