In commit title: we use the "arm64: morello:" tag when updating this
defconfig (see previous commits touching this file).

Noted.

We try to update this defconfig according to the output of `make
savedefconfig`, so that it remains stable and easy to diff. In that
output, it looks like these two entries are just before CONFIG_9P_FS,
not after.

Sure, I will address this in V2 as well.

Thanks for the feedback.
