perf evsel: Support perf_evsel__open(cpus > 1 && threads > 1)
And a test for it: [acme@felicio linux]$ perf test 1: vmlinux symtab matches kallsyms: Ok 2: detect open syscall event: Ok 3: detect open syscall event on all cpus: Ok [acme@felicio linux]$ Translating C the test does: 1. generates different number of open syscalls on each CPU by using sched_setaffinity 2. Verifies that the expected number of events is generated on each CPU It works as expected.
