gcc -O3 warns that some local variables are not properly initialized:
drivers/scsi/fnic/vnic_dev.c: In function 'fnic_dev_hang_notify':
drivers/scsi/fnic/vnic_dev.c:511:16: error: 'a0' is used uninitialized in this function [-Werror=uninitialized]
vdev->args[0] = *a0;

Apparently the code relies on the local variables occupying adjacent memory
locations in the same order, but this is of course not guaranteed.
Use an array of two u64 variables where needed to make it work correctly.
I suspect there is also an endianness bug here, but have not digged in deep
enough to be sure.

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.
