Note:
I'm using perf_sw_context in difference to perf_invalid_context
(see WARN_ON in perf_pmu_register). Reason is that with perf_invalid_context
add() is never called and the counter results are shown as "unsupported" by
perf. With perf_sw_context everything works as expected.

What?! All the uncore PMUs use perf_invalid_context. What doesn't work
for you?

As I said, perf reports the values as "unsupported". But as Mark pointed
out, I wasn't using -a switch, just "perf stat -e \thunderx_lmc\blah\ -- ...".
