My patch didn't resolve the Marvell issue, it just resolved other
cases that could also lead to the same problem.

I added a line to my kernel parameters to blacklist the Marvell
console.  I wasn't sure if blacklisting would have been acceptable.
That is why I called out that I still had to add that line to my
kernel in the cover letter for my patch set.
