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.
