Subject: linux-next: build failure after merge of the perf tree

Hi all,

After merging the perf tree, today's linux-next build (arm64 perf)
failed like this:

Exception processing /tmp/next/perf/pmu-events/arch/arm64/arm/cortex-a510/pmu.json
Traceback (most recent call last):

   a66f6242fbf52 (perf vendor events arm64: Remove uncountable events)

I have used the perf tree from 20260116 instead.
