Pulled the second patch, with the above two fixes as well; thanks!

I don't know anything about PPC, so I'll let someone else confirm all
that before pulling, but it sounds reasonable.

Nit, but I don't think these should be different list items, but rather
simply different paragraphs in the same item.

These two lines need swapping as pointed out by Matt, or just removing;
not every sentence needs to be its own paragraph :P

Here and in the previous sentence, just say "if supported" instead of
repeating the name of the feature :)

Someone can fix-up on commit -- the  and  are reversed here.

Power8, Power8NV, and Power9 are supported on an equal footing
with X86.
