perf/core improvements:

Browse source 
User visible:
 
 - Add "srcline_from" and "srcline_to" branch sort keys to 'perf top' and
   'perf report' (Andi Kleen)
 
 Infrastructure:
 
 - Make 'perf trace' auto-attach fd->name and ptr->name beautifiers based
   on the name of syscall arguments, this way new syscalls that have
   'const char * (path,pathname,filename)' will use the fd->name beautifier
   (vfs_getname perf probe, if in place) and the 'fd->name' (vfs_getname
   or via /proc/PID/fd/) (Arnaldo Carvalho de Melo)
 
 - Infrastructure to read from a ring buffer in backward write mode (Wang Nan)
