Yeah I decided those were bug fixes so could be taken separately.

I didn't feel I could take patch 1 via the powerpc tree without risking
conflicts.

Andrew could take patch 1 and 4 via mm, though he might not want to pick
them up this late.

I guess step one would be to repost 1 and 4 as a new series. Either they
can go via mm, or for 5.15 I could probably take them both as long as I
pick them up early enough.
