Avoid error prone cpu_map + idx variant. Remove now unused functions.At this point we need to remove the now unused perf_env__get_cpu(), and then deal with the fallout in the following patches that needlessly modify this unused function. Doing that now.
Done, force pushed to tmp.perf/perf_cpu, now it is going again thru the build containers, a better start now: [perfbuilder@five ~]$ export BUILD_TARBALL=http://192.168.100.2/perf/perf-5.16.0.tar.xz [perfbuilder@five ~]$ time dm 1 95.61 almalinux:8 : Ok gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-4) , clang version 12.0.1 (Red Hat 12.0.1-4.module_el8.5.0+1025+93159d6c) 2 56.18 alpine:3.4 : Ok gcc (Alpine 5.3.0) 5.3.0 , clang version 3.8.0 (tags/RELEASE_380/final) 3: alpine:3.5 - Arnaldo
