This reverts commit9e0f9464e2("drm/i915/gem: Async GPU relocations only"), and related commit7ac2d2536d("drm/i915/gem: Delete unused code"). Async GPU relocations are not the path forward, we want to remove GPU accelerated relocation support eventually when userspace is fixed to use VM_BIND, and this is the first step towards that. We will keep async gpu relocations around for now, until userspace is fixed. Relocation support will be disabled completely on platforms where there was never any userspace that depends on it, as the hardware doesn't require it from at least gen9+ onward. For older platforms, the plan is to use cpu relocations only. The igt side is fixed in igt commit 39e9aa1032a4e ("tests/i915: Remove subtests that rely on async relocation behavior").

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.
