Hi all,
Since this came up yet again recently, and it's an idea which has been nagging me for years, I decided it was time to see how hard it really would be to start shaving this yak. And it turns out to be refreshingly simple - the core code has quietly become capable of doing most of what we want, the one new functional addition is trivial (patch #2), and the resulting largely-mechanical cleanup seems a pretty nice win.
This series is focused on drivers/perf/ as that's where most mess is concentrated, but figured I'd include the arch/ patches as well since they might be reasonable to land with the core changes, at least for x86 (FWIW I did also look at the powerpc drivers but they scared me and I ran away; sorry). The remaining stragglers elsewhere around the tree I'd come back to as a follow-up.
(And yes, I appreciate it's mid-merge-window already, but since I do have a tree-wide rename proposed here, may as well give the discussion a chance for a head start before -rc1...)
Thanks, Robin.
