Here's a bunch of patches that have been on the list in various
forms, but haven't made it upstream yet. I would like to get
them merged for 9.0 if possible. The checkstop and attn ones are
bigger but they're not so important so I could defer them.

Main change is merging Ben's DEXCR patch from last year with my
POWER10 pa-features patch -- his was posted first and added a
POWER10 entry so I took his but updated title and changelog.

And changing the SAO and copy-paste patches to always cease
advertising them, rather than depending on the host, as per
discussion with David.

Thanks,
Nick

Yes please! Series LGTM but I don't have enough PPC knowledge
to give a proper R-b, so I'll let more familiar developers.

Phil.
