Please repost anything not yet applied in V2 of the series.

Makes it much easier for me to avoid missing patches!

This is fine but it needs to be in the original comment changing patch
rather than removing the comments first then a few patches later putting
back a different version.

So good change but in the wrong place in the series.  Learning to reorder
a series and merge down multiple patches into one is very useful when
working with git.
