perf/core improvements and fixes
. kcore annotation improvements, including build-id cache support,
multi map 'call' instruction navigation fixes, kcore address
validation, objdump workarounds. From Adrian Hunter.
. 'trace' beautifiers for lots of syscall arguments.
. More compact 'trace' output by suppressing zeroed args.
. Show thread COMM by default in 'trace'.
. Show path associated with fd in live sessions, using a 'vfs_getname'
'perf probe' created dynamic tracepoint or by looking at /proc/pid/fd.
. Memory and mmap leak fixes from Chenggang Qin.
. Add option to show full timestamp in 'trace', from David Ahern.
. Add 'record' command in 'trace', to record raw_syscalls:*, from David Ahern.
. Add summary option to dump syscall statistics in 'trace', from David Ahern.
. Fix comm resolution in 'trace' when reading events from file, from David Ahern.
. Improved messages when doing profiling in all or a subset of CPUs
using a workload as the session delimitator, as in:
'perf stat --cpu 0,2 sleep 10s'
. Add units to nanosec-based counters in 'perf stat', from David Ahern.
. Assorted build fixes for from David Ahern and Jiri Olsa.
. 'perf lock' fixes and cleanups, from Davidlohr Bueso.
. Memory leak fixes in 'perf test', from Felipe Pena.
. Build system super speedups, from Ingo Molnar.
. Fix mmap_read event overflow, from Jiri Olsa.
. Code cleanups from Jiri Olsa.
. Allow specifying B/K/M/G unit to the --mmap-pages arguments, from Jiri Olsa.
. Separate the GTK support in a separate libperf-gtk.so DSO, that is
only loaded when --gtk is specified, from Namhyung Kim.
. Fixes for some memory leaks, from Namhyumg Kim.
. Fix srcline sort key behavior, from Namhyung Kim.
. Fix failing assertions in numa bench, from Petr Holasek.
. perf bash completion fixes and improvements from Ramkumar Ramachandra.
. Improve error messages in 'trace', providing hints about system configuration
steps needed for using it, from Ramkumar Ramachandra.
. Remove bogus info when using 'perf stat' -e cycles/instructions, from
Ramkumar Ramachandra .
. Support for Openembedded/Yocto -dbg packages, from Ricardo Ribalda Delgado.
. Implement addr2line directly using libbfd, from Roberto Vitillo.
. Add new option --ignore-vmlinux for perf top, from Willy Tarreau.
