This snippet seems to be based on commit 18d98a79382c ("parisc: Enable KASLR").

Perhaps this Saturday is off to an even slower start than usual for me but that commit summary appears to be typoed as the commit itself apparently enables userspace ASLR for PA-RISC. Or did I misunderstand the commit?

You're not missing anything, you're correct.

But now that I think about it, what better way to celebrate the 14 year anniversary of PaX adding ASLR support to PARISC than to do it in 2017 after the architecture is already dead, with the wrong acronym.

We can file that under the same achievement column as Andy/Linus/Ingo et al "reinventing" PaX's marking of the GDT as read-only and musing in public about whether it's possible to do while patting themselves on the back for their innovation -- PaX did it as early as 2003 (possibly even earlier, but my archives don't go back further than that). All this while "improving" KASLR yet again, while they all sheepishly ignore the numerous presentations from last year and earlier about how completely pointless it is, with attacks demonstrating exactly we had already told them back in 2011. It's PR-focused mental masturbation, not security, if the "defenses" they spend so much time on aren't even a road block for script kids who can run some off-the-shelf code.
