i915_gem_object_create_internal() does not hand out zeroed memory. Thus we may confuse whatever stale garbage is in there as a previous register write and mistakenly handle the first actual register write as an indexed write. This can end up corrupting the instruction sufficiently well to lose the entire register write. Make sure we've actually emitted a previous instruction before attemting indexed register write merging.

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.
