perf fails to build with this error:

which is due to commit 07511f3c23cdaf1dbb44802f026fcc476351dfe2 ("perf tools: Use perf_env__get_cpu_topology() in machine__resolve()"), it looks like we need to also backport those commits:
751835c57632006232bf30405cd7201dceb0b8e0 ("perf stat: Introduce perf_env__get_cpu_topology() to guard NULL env->cpu")
6d18804b963b78dcd53851f11e9080408b3d85c2 ("perf cpumap: Give CPUs their own type")
c760174401f605cf63314d3817069a40945f0e0b ("perf cpumap: Reduce cpu size from int to int16_t")
