Takashi Sakamoto 526e21a2aa firewire: ohci: add tracepoints event for data of Self-ID DMA 
In 1394 OHCI, the SelfIDComplete event occurs when the hardware has
finished transmitting all of the self ID packets received during the bus
initialization process to the host memory by DMA.

This commit adds a tracepoints event for this event to trace the timing
and packet data of Self-ID DMA. It is the part of following tracepoints
events helpful to debug some events at bus reset; e.g. the issue addressed
at a commit d0b06dc48f ("firewire: core: use long bus reset on gap count
error")[1]:

* firewire_ohci:irqs
* firewire_ohci:self_id_complete
* firewire:bus_reset_handle
* firewire:self_id_sequence

They would be also helpful in the problem about invocation timing of
hardIRQ and process (workqueue) contexts. We can often see this kind of
problem with -rt kernel[2].

README 

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 reStructuredText 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.
