mainlining shenanigans

In quite a few places, we have a list iteration over the vma on an object that only want to inspect GGTT vma. By construction, these are placed at the start of the list, so we have copied that knowledge into many callsites. Pull that knowledge back to i915_vma.h and provide a for_each_ggtt_vma() to tidy up the code. v2: Add a backreference from vma_create() to remind ourselves why we put ggtt vma at the head of the obj->vma_list (and ppgtt vma at the tail). v3: Fixup s/vma/V/ Suggested-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20171207211407.31549-1-chris@chris-wilson.co.uk |

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.
