       "A second (and last) round of late coming fixes and changes, almost all
        of them in perf tooling:
      
        User visible tooling changes:
      
         - Add period data column and make it default in 'perf script' (Jiri
           Olsa)
      
         - Add a visual cue for toggle zeroing of samples in 'perf top'
           (Taeung Song)
      
         - Improve callchains when using libunwind (Namhyung Kim)
      
        Tooling fixes and infrastructure changes:
      
         - Fix for double free in 'perf stat' when using some specific invalid
           command line combo (Yasser Shalabi)
      
         - Fix off-by-one bugs in map->end handling (Stephane Eranian)
      
         - Fix off-by-one bug in maps__find(), also related to map->end
           handling (Namhyung Kim)
      
         - Make struct symbol->end be the first addr after the symbol range,
           to make it match the convention used for struct map->end.  (Arnaldo
           Carvalho de Melo)
      
         - Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
           live' (Jiri Olsa)
      
         - Fix python test build by moving callchain_param to an object linked
           into the python binding (Jiri Olsa)
      
         - Document sysfs events/ interfaces (Cody P Schafer)
      
         - Fix typos in perf/Documentation (Masanari Iida)
      
         - Add missing 'struct option' forward declaration (Arnaldo Carvalho
           de Melo)
      
         - Add option to copy events when queuing for sorting across cpu
           buffers and enable it for 'perf kvm stat live', to avoid having
           events left in the queue pointing to the ring buffer be rewritten
           in high volume sessions.  (Alexander Yarygin, improving work done
           by David Ahern):
      
         - Do not include a struct hists per perf_evsel, untangling the
           histogram code from perf_evsel, to pave the way for exporting a
           minimalistic tools/lib/api/perf/ library usable by tools/perf and
           initially by the rasd daemon being developed by Borislav Petkov,
           Robert Richter and Jean Pihet.  (Arnaldo Carvalho de Melo)
      
         - Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
           thread maps mean syswide monitoring, reducing the boilerplate for
           tools that only want system wide mode.  (Arnaldo Carvalho de Melo)
      
         - Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
           should be just a front end for exit + free (Arnaldo Carvalho de
           Melo)

      The check for the presence or not of the optional switch function
      get_phy_flags() called the function, rather than checked to see if it
      is a NULL pointer. This causes a derefernce of a NULL pointer on all

      sparc64: Do not define thread fpregs save area as zero-length array. · e2653143
      David S. Miller authored
      This breaks the stack end corruption detection facility.
      
      What that facility does it write a magic value to "end_of_stack()"
      and checking to see if it gets overwritten.
      
      "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
      the beginning of the FPU register save area.
      
      So once the user uses the FPU, the magic value is overwritten and the
      debug checks trigger.
      
      Fix this by making the size explicit.
      
      Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
      are limited to 7 levels of FPU state saves.  So each FPU register set
      is 256 bytes, allocate 256 * 7 for the fpregs area.

      sparc64: Fix corrupted thread fault code. · 84bd6d8b
      David S. Miller authored
      Every path that ends up at do_sparc64_fault() must install a valid
      FAULT_CODE_* bitmask in the per-thread fault code byte.
      
      Two paths leading to the label winfix_trampoline (which expects the
      FAULT_CODE_* mask in register %g4) were not doing so:
      
      1) For pre-hypervisor TLB protection violation traps, if we took
         the 'winfix_trampoline' path we wouldn't have %g4 initialized
         with the FAULT_CODE_* value yet.  Resulting in using the
         TLB_TAG_ACCESS register address value instead.
      
      2) In the TSB miss path, when we notice that we are going to use a
         hugepage mapping, but we haven't allocated the hugepage TSB yet, we
         still have to take the window fixup case into consideration and
         in that particular path we leave %g4 not setup properly.
      
      Errors on this sort were largely invisible previously, but after
      commit 4ccb9272 ("sparc64: sun4v TLB
      error power off events") we now have a fault_code mask bit
      (FAULT_CODE_BAD_RA) that triggers due to this bug.
      
      FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS
      (see #1 above) and thus we get seemingly random bus errors triggered
      for user processes.
