perf tools: Default to python version 2 (2014-08-04 12:21:37 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
. Show better error message in case we fail to open counters due to EBUSY error,
for instance, when oprofile is running. (Jiri Olsa)
. Honour -w in the report tools (report, top), allowing to specify the widths
for the histogram entries columns. (Namhyung Kim)
. Don't run workload if not told to, as happens when the user has no
permission for profiling and even then the specified workload ends
up running (Arnaldo Carvalho de Melo)
. Do not ignore mmap events in 'perf kmem report'. This tool was using
the kernel mmaps in the running machine instead of processing the mmap
records from the perf.data file. (Namhyung Kim)
. Properly show submicrosecond times in 'perf kvm stat' (Christian Borntraeger)
. Allow the user to disable time stamps in 'perf record' (Andi Kleen)
. Make sure --symfs usage includes the path separator (Arnaldo Carvalho de Melo)
Developer Stuff:
. Fix arm64 build error (Mark Salter)
. Fix make PYTHON override (Namhyung Kim)
. Rename ordered_samples to ordered_events and allow setting a queue
size for ordering events (Jiri Olsa)
. Default to python version 2 (Thomas Ilsche)
