i915_gem_detect_bit_6_swizzle() tries to hide unknown swizzling from userspace (and ourselves) leaving us with the only clue inside i915->quirks & QUIRK_PIN_SWIZZLED_PAGES. If we see this bit set, it means that we really have no clue as to what the swizzle pattern is being used in any one page and so cannot compute what the reference value should be in our tiling selftests. We have to skip the test.

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.
