[ Upstream commit 4919b33b63c8b69d8dcf2b867431d0e3b6dc6d28 ] The adapter info MAD is used to send the client info and receive the host info as a response. A persistent buffer is used and as such the client info is overwritten after the response. During the course of a normal adapter reset the client info is refreshed in the buffer in preparation for sending the adapter info MAD. However, in the special case of LPM where we reenable the CRQ instead of a full CRQ teardown and reset we fail to refresh the client info in the adapter info buffer. As a result, after Live Partition Migration (LPM) we erroneously report the host's info as our own.

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.
