In commit 1d3351e6 ("perf tools: Enable on a list of CPUs for hybrid") perf on hybrid will warn if a user requested CPU doesn't match the PMU of the given event but only for hybrid PMUs. Make the logic generic for all PMUs and remove the hybrid logic. Warn if a CPU is requested that isn't present/offline for events not on the core. Warn if a CPU is requested for a core PMU, but the CPU isn't within the cpu map of that PMU. For example on a 16 (0-15) CPU system: ``` $ perf stat -e imc_free_running/data_read/,cycles -C 16 true WARNING: A requested CPU in '16' is not supported by PMU 'uncore_imc_free_running_1' (CPUs 0-15) for event 'imc_free_running/data_read/' WARNING: A requested CPU in '16' is not supported by PMU 'uncore_imc_free_running_0' (CPUs 0-15) for event 'imc_free_running/data_read/' WARNING: A requested CPU in '16' is not supported by PMU 'cpu' (CPUs 0-15) for event 'cycles' Performance counter stats for 'CPU(s) 16': <not supported> MiB imc_free_running/data_read/ <not supported> cycles 0.000575312 seconds time elapsed ``` Remove evlist__fix_hybrid_cpus that previously produced the warnings and also perf_pmu__cpus_match that worked with evlist__fix_hybrid_cpus to change CPU maps for hybrid CPUs, something that is no longer necessary as CPU map propagation properly intersects user requested CPUs with the core PMU's CPU map.
