Chris Wilson a69ab52b03 drm/i915: Remove extra waiter kick on legacy resets
Now with a more efficacious workaround for the lost interrupts after
reset, we can remove the hack of kicking the waiters after reset. The
issue was that the kick only worked for the immediate window after the
reset (those seqno that would complete in the time it took for the
waiter thread to perform its check) but miss any seqno that lacked an
interrupt afterwards.

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.
