So symbol 'pmu_sys_event_tables' is introduced inhttps://lore.kernel.org/linux-arm-kernel/1607080216-36968-3-git-send-email-john.garry@xxxxxxxxxx/,
but I did not think that you picked any of this series up yet, right?

I checked your perf/core branch, and no sign, so which git/branch is this?
Its unpublished, I'll send it to the tmp.perf/core branch now.

I use cross-compile for arm64 to build, and it's ok.

I notice that the failures are for architectures which don't have an entry under pmu-events/arch, so maybe we're missing some 'weak' definition of pmu_sys_event_tables.

I'll check now.
