Agreed, though I don't think we have a clear proposal as to what
else to remove.

Mmm ... I'd agree that the relevant stanzas of s_lock.h/.c haven't
changed in a long time, but port/atomics/ is of considerably newer
vintage and is still receiving a fair amount of churn. Moreover,
much of what I proposed to remove from there is HPPA-only code with
exactly no parallel in other arches (specifically, the bits in
atomics/fallback.h). So I don't feel comfortable that it will
continue to work without benefit of testing. We're taking a risk
just hoping that it will continue to work in the back branches until
they hit EOL. Expecting that it'll continue to work going forward,
sans testing, seems like the height of folly.
