Dick Kennedy 86ee57a97a scsi: lpfc: Fix kdump hang on PPC
When the kdump kernel shuts down lpfc calls flush_work_queue on an
interrupt to schedule the cq handler. When there is only one CPU active on
the kdump kernel, it is possible for the work_on to get scheduled on a
non-active CPU causing it to never be scheduled.

When in the kdump environment, per-CPU affinity of cq's to cpus is not
necessary. In those cases, use a general queue_work rather than a
queue_work_on().

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.
