What's the plan for getting it merged? Seems we don't have one?

Yeah, so far there is no plan. I'm not really sure who's attention I need to get or how to get it.

Given it touches two arches and generic stuff and drivers and crypto,
it's a bit of a mess to merge. It's not really something I want to merge
via the powerpc tree.


Is there any way to split it? I couldn't immediately see what the hard
dependencies were between the patches.

Yes, a couple of patches have already been taken by their maintainers over the last few cycles.

eg. It looks like I could take the two powerpc patches on their own for
4.17, and then the rest could go via other trees?

Yup! If you can take the powerpc patches I can keep trying to get the rest in. They are largely independent and shouldn't really change anything without the following patches.

Is patch 1 stand alone?

Essentially, yes, but patch 5 depends on it seeing it's changing the same area and is trying to avoid creating the same kbuild warnings that patch 1 suppresses.

The other option is to ask Andrew Morton to take it, as he often carries
these cross-tree type series.

Thanks for the tip! I'll copy him when I repost it after the merge window.
