perf fails to build with:

CC /local/users/fainelli/buildroot/output/arm/build/linux-custom/tools/perf/util/evsel.o
util/evsel.c: In function 'evsel__set_count':
util/evsel.c:1505:14: error: 'struct perf_counts_values' has no member named
'lost'
1505 | count->lost = lost;
| ^~
make[6]: *** [/local/users/fainelli/buildroot/output/arm/build/linux-custom/tools/build/Makefile.build:97: /local/users/fainelli/buildroot/output/arm/build/linux-custom/tools/perf/util/evsel.o]
Error 1

seems like we need to backport upstream
89e3106fa25fb1b626a7123dba870159d453e785 ("libperf: Handle read format in
perf_evsel__read()") to add the 'lost' member.

Is this new? I can't build perf on any older kernels, but others might
have better luck...

Yes this is a new build failure, caused by "perf tools: Support reading PERF_FORMAT_LOST" AFAICT.
