Ingo Molnar b89e7914f0 perf/core improvements and fixes: 
- Show only failing syscalls with 'perf trace --failure' (Arnaldo Carvalho de Melo)
 
 	e.g: See what 'openat' syscalls are failing:
 
   # perf trace --failure -e openat
    762.323 ( 0.007 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video2) = -1 ENOENT No such file or directory
    <SNIP N /dev/videoN open attempts... sigh, where is that improvised camera lid?!? >
    790.228 ( 0.008 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video63) = -1 ENOENT No such file or directory
   ^C#
 
 - Show information about the event (freq, nr_samples, total period/nr_events) in
   the annotate --tui and --stdio2 'perf annotate' output, similar to the
   first line in the 'perf report --tui', but just for the samples for a
   the annotated symbol (Arnaldo Carvalho de Melo)
 
 - Introduce 'perf version --build-options' to show what features were
   linked, aliased as well as a shorter 'perf -vv' (Jin Yao)
 
 - Add a "dso_size" sort order (Kim Phillips)
 
 - Remove redundant ')' in the tracepoint output in 'perf trace' (Changbin Du)
 
 - Synchronize x86's cpufeatures.h, no effect on toolss (Arnaldo Carvalho de Melo)
