1.8.1 release notes point to the wrong tarball/zip

[ngrewe]

Hi David,

I just noticed that links for the archives in the 1.8.1 release notes still point to the 1.8 release.

Cheers,

Niels

Ooops. I plan on tweaking the way we do memory allocation for blocks-as-imps soon (which will remove the need for mapping the page in two different places and simplify porting), so I'll push out a 1.8.2 release once that's done. Unfortunately, I can't fix them in 1.8.2 without regenerating the tarballs, which will break packaging.

That sounds cool. I'm interested in seeing how that works in the presence of W^X policies…

It's quite simple (not sure what the performance impact will be - we'll use more TLB entries, but pollute the i-cache less). Rather than having each page contain data then trampoline code interleaved, we'll have one page of data followed by one page of the trampoline code. All of the ISAs that we care about can do loads with a 4KB displacement easily, so the two loads will be from pc-4KB.

Hmm, a release is long overdue. I think the latest commit should fix the alignment issues. Most of the changes in the current ANNOUNCE file were things I did last Christmas, so I'll aim to push out a new release once I've seen some evidence that things are working again.

Closing - it's a real issue, but I can't fix it without changing the hashes of the tarballs, which will break any downstream packages.
