Hi Andrew,

A couple of minor comments regarding the -mm tree commit message
reformatting...

The benchmark table above has been collapsed, making it mostly
incomprehensible.

The reordering of the tags above is also somewhat confusing - I added
the [ddiss@xxxxxxx: rebase atop ...] to reflect minor changes that I
made to the patch *after* Martin had provided his Reviewed-by tag.
