We only need to apply the BIAS for self-relocations into the batchbuffer iff the execobject has any relocations. This suppresses some warnings we may get with a full gtt (so the batch object has wound up at 0 from a previous invocation), but doesn't fix the underlying problem of how we tried to move a pinned batch vma (how we have a pinned user vma outside of execbuf, I do not know, though this being on an aliasing ppgtt means it could be a spurious pinning via the global gtt). One step at a time...

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.
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.
