Hi all,

Today's linux-next boot test on a Power7 blade produced this message

There are no changes to the ehea driver relative to Linus' tree.  ehea
was built as a module and it looks like this is the first module being
loaded.

Maybe the module parameter alignment patches?  That is a very strange
parameter name (it is the same in the other messages).
