We generally omit register polling from the i915_reg_rw tracepoint. Understandable since polling could generate a lot of noise in the trace. The downside is that the trace is incomplete. As a compromise let's trace the final register value observed while polling. That should be generally sufficient to observe what the code should be doing next. I suppose in some cases it might make sense to also trace the initial register value, and maybe the number of times we polled. But that would require a separate tracepoint so let's leave it for the future. The other users of _NOTRACE() are i915_pmu and i2c bitbanging, which I decided to leave alone. Next we should do something to claw back the tracepoints for planes and whatnot which were switched to _FW() a while back. I guess just new macros for raw_rw+trace. The question is what to call it?

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.
