Subject: [PATCH 00/10] perf: Clean up common uncore boilerplate

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.
