User visible:
- Beautify more syscall arguments in 'perf trace', using the type column in
tracepoint /format fields to attach, for instance, a pid_t resolver to the
thread COMM, also attach a mode_t beautifier in the same fashion
(Arnaldo Carvalho de Melo)
- Build the syscall table id <-> name resolver using the same .tbl file
used in the kernel to generate headers, to avoid the delay in getting
new syscalls supported in the audit-libs external dependency, done so
far only for x86_64 (Arnaldo Carvalho de Melo)
- Improve the documentation of event specifications (Andi Kleen)
- Process update events in 'perf script', fixing up this use case:
# perf stat -a -I 1000 -e cycles record | perf script -s script.py
- Shared object symbol adjustment fixes, fixing symbol resolution in
Android (Wang Nan)
Infrastructure:
- Add dedicated unwind addr_space member into thread struct, to allow
tools to use thread->priv, noticed while working on having callchains
in 'perf trace' (Jiri Olsa)
Build fixes:
- Fix the build in Ubuntu 12.04 (Arnaldo Carvalho de Melo, Vinson Lee)
