Subject: [PATCH 5.10 045/717] perf test: Use generic event for expand_libpfm_events()

From: Namhyung Kim <namhyung@...nel.org>

[ Upstream commit 9b0a7836359443227c9af101f7aea8412e739458 ]

I found that the UNHALTED_CORE_CYCLES event is only available in the
Intel machines and it makes other vendors/archs fail on the test.  As
libpfm4 can parse the generic events like cycles, let's use them.

Fixes: 40b74c30ffb9 ("perf test: Add expand cgroup event test")
