Ingo Molnar 69766c40c3 perf/urgent fixes:

User visible fixes:
 
 - Fix the lookup for a kernel module in 'perf probe', fixing for instance, the
   erroneous return of "[raid10]" when looking for "[raid1]"  (Konstantin Khlebnikov)
 
 - Disable counters in a group before reading them in 'perf stat', to avoid skew (Mark Rutland)
 
 - Fix adding probes to function aliases in systems using kaslr (Masami Hiramatsu)
 
 - Trip libtraceevent trace_seq buffers, removing unnecessary memory usage that could
   bring a system using tracepoint events with 'perf top' to a crawl, as the trace_seq
   buffers start at a whooping 4 KB, which is very rarely used in perf's usecases,
   so realloc it to the really used space as a last measure after using libtraceevent
   functions to format the fields of tracepoint events (Arnaldo Carvalho de Melo)
 
 - Fix 'perf probe' location when using DWARF on ppc64le (Ravi Bangoria)
 
 Improvement:
 
 - Allow specifying signedness casts to a 'perf probe' variable, to shorten
   the number of steps to see signed values that otherwise would always appear
   as hex values (Naohiro Aota)
 
 Documentation fixes:
 
 - Add 'bpf-output' field to 'perf script' usage message (Brendan Gregg)
 
 Infrastructure fixes:
 
 - Sync kernel header files: cpufeatures.h, {disabled,required}-features.h,
   bpf.h and vmx.h, so that we get a clean build, without warnings about files
   being different from the kernel counterparts.
 
   A verification of the need or desirability of changes in tools/ based on what
   was done in the kernel changesets was made and documented in the respective
   file sync changesets (Arnaldo Carvalho de Melo)
