Chris Wilson d822bb18ce drm/i915: intel_ring.engine is unused
Or rather it is used only by intel_ring_pin() to extract the
drm_i915_private which we can easily pass in. As this is a relatively
rare operation, save the space in the struct, and as such it is even
break even in the extra code for passing around the parameter:

add/remove: 0/0 grow/shrink: 2/3 up/down: 15/-15 (0)
function                                     old     new   delta
intel_init_ring_buffer                       906     918     +12
execlists_context_pin                       1308    1311      +3
mock_engine                                  407     403      -4
intel_engine_create_ring                     367     363      -4
intel_ring_pin                               326     319      -7
Total: Before=1261794, After=1261794, chg +0.00%

v2: Reorder intel_init_ring_buffer to keep the ring setup together:

add/remove: 0/0 grow/shrink: 2/3 up/down: 9/-15 (-6)
function                                     old     new   delta
intel_init_ring_buffer                       906     912      +6
execlists_context_pin                       1308    1311      +3
mock_engine                                  407     403      -4
intel_engine_create_ring                     367     363      -4
intel_ring_pin                               326     319      -7
Total: Before=1261794, After=1261788, chg -0.00%

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
