      perf: Unified API to record selective sets of arch registers · c5e63197
      Jiri Olsa authored
      This brings a new API to help the selective dump of registers on event
      sampling, and its implementation for x86 arch.
      
      Added HAVE_PERF_REGS config option to determine if the architecture
      provides perf registers ABI.
      
      The information about desired registers will be passed in u64 mask.
      It's up to the architecture to map the registers into the mask bits.
      
      For the x86 arch implementation, both 32 and 64 bit registers bits are
      defined within single enum to ensure 64 bit system can provide register
      dump for compat task if needed in the future.

      Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
      
      Pull perf/core fixes and some late updates from Arnaldo Carvalho de Melo:
      
       * Make clean brace expansion fix for some shells, from Palmer Cox
      
       * Warn user just once per guest kernel when not finding kernel info,
         from David Ahern
      
       * perf test fix from Jiri Olsa
      
       * Fix error handling on event creation in perf top, from David Ahern
      
       * Fix check on perf_target__strnerror, from Namhyung Kim
      
       * Save the whole cmdline, from David Ahern
      
       * Prep work for the DWARF CFI post unwinder, so that it doesn't
         uses perf_session in lots of places, just evlist/evsel is enough.
