Currently, cpu_map[cpu#]->hdwq is left to equal LPFC_VECTOR_MAP_EMPTY for
not present CPUs. If a CPU is dynamically hot-added, it is possible we may
crash due to not assigning an allocated hdwq.
Correct by assigning a hdwq at initialization for all not-present CPUs.

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.
