It turns out both the hp.com link and the arm.com link now redirect to marketing pages, so instead of chasing forever, I decided to take them out.
HPPA and ARM maintainers on copy, if you want to add more appropriate links, we can definitely do so of course, though I'd argue with none of our users or developers raising this, probably not a lot of interest in those specifically?
