Anything received after that time might be too late.

The whole patch series can be found in one patch at:

perf does not build on ARM and ARM64 with:

util/evsel.h: In function 'perf_evsel__has_branch_hw_idx':
util/evsel.h:387:54: error: 'PERF_SAMPLE_BRANCH_HW_INDEX' undeclared (first use in this function); did you mean 'PERF_SAMPLE_BRANCH_IN_TX'? 387 | return evsel->core.attr.branch_sample_type & PERF_SAMPLE_BRANCH_HW_INDEX; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ | PERF_SAMPLE_BRANCH_IN_TX util/evsel.h:387:54: note: each undeclared identifier is reported only once for each function it appears in

dropping 946b6643e67f552a9966a06ab5a9032120eeeea9 ("perf tools: Add hw_idx in struct branch_stack") allows me to build again for ARM and ARM64, howevef for MIPS we also have:

50a3ffda05679c55929bf2bdebc731dfafe3221b ("perf hist: Add missing puts to hist__account_cycles") failing to build with:

util/hist.c:2600:5: warning: nested extern declaration of 'maps__put' [-Wnested-externs] util/hist.c:2600:23: error: 'struct addr_map_symbol' has no member named 'ms'
     maps__put(bi[i].to.ms.maps);
                       ^
util/hist.c:2601:24: error: 'struct addr_map_symbol' has no member named 'ms'
     map__put(bi[i].from.ms.map);
                        ^
util/hist.c:2602:25: error: 'struct addr_map_symbol' has no member named 'ms'
     maps__put(bi[i].from.ms.maps);
                         ^

so I would suggest we just revert both commits. Once we do that, all is well for ARM, ARM64 and MIPS.
