Subject: [PATCH 0/5] perf: oprofile spring cleanup
Date: Wed, 14 Apr 2021 14:44:04 +0100	[thread overview]
Message-ID: <20210414134409.1266357-1-maz@kernel.org> (raw)

This small series builds on top of the work that was started with [1].

It recently became apparent that KVM/arm64 is the last bit of the
kernel that still uses perf_num_counters().

As I went ahead to address this, it became obvious that all traces of
oprofile had been eradicated from all architectures but arm64, s390
and sh (plus a bit of cruft in the core perf code). With KVM fixed,
perf_num_counters() and perf_pmu_name() are finally gone.

Thanks,

	M.
