Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Add ability to specify to select which registers to record, to reduce the size of perf.data files, and also allow printing the registers in 'perf script': (Stephane Eranian) # perf record --intr-regs=AX,SP usleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.016 MB perf.data (8 samples) ] # perf script -F ip,sym,iregs | tail -5 ffffffff8105f42a native_write_msr_safe AX:0xf SP:0xffff8802629c3c00 ffffffff8105f42a native_write_msr_safe AX:0xf SP:0xffff8802629c3c00 ffffffff81761ac0 _raw_spin_lock AX:0xffff8801bfcf8020 SP:0xffff8802629c3ce8 ffffffff81202bf8 __vma_adjust_trans_huge AX:0x7ffc75200000 SP:0xffff8802629c3b30 ffffffff8122b089 dput AX:0x101 SP:0xffff8802629c3c78 # Infrastructure changes: - Open event on evsel cpus and threads.
