Ingo Molnar 21f77d231f perf/core improvements and fixes:
User visible:
 
 - Honour the kernel.perf_event_max_stack knob more precisely by not counting
   PERF_CONTEXT_{KERNEL,USER} when deciding when to stop adding entries to
   the perf_sample->ip_callchain[] array (Arnaldo Carvalho de Melo)
 
 - Fix identation of 'stalled-backend-cycles' in 'perf stat' (Namhyung Kim)
 
 - Update runtime using 'cpu-clock' event in 'perf stat' (Namhyung Kim)
 
 - Use 'cpu-clock' for cpu targets in 'perf stat' (Namhyung Kim)
 
 - Avoid fractional digits for integer scales in 'perf stat' (Andi Kleen)
 
 - Store vdso buildid unconditionally, as it appears in callchains and
   we're not checking those when creating the build-id table, so we
   end up not being able to resolve VDSO symbols when doing analysis
   on a different machine than the one where recording was done, possibly
   of a different arch even (arm -> x86_64) (He Kuang)
 
 Infrastructure:
 
 - Generalize max_stack sysctl handler, will be used for configuring
   multiple kernel knobs related to callchains (Arnaldo Carvalho de Melo)
 
 Cleanups:
 
 - Introduce DSO__NAME_KALLSYMS and DSO__NAME_KCORE, to stop using
   open coded strings (Masami Hiramatsu)
