  perf record: Add ability to name registers to record (2015-08-31 18:01:33 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- 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
