         - Fix inconsisten config dependcy/select magic for the MFD_CS5535
           driver.
      
         - Fix a corruption of the physical address space bits when encryption
           has reduced the address space and late cpuinfo updates overwrite
           the reduced bit information with the original value.
      
         - Dominiks syscall rework which consolidates the architecture
           specific syscall functions so all syscalls can be wrapped with the
           same macros. This allows to switch x86/64 to struct pt_regs based

         - Introduce 'perf version --build-options' to show what features were
           linked, aliased as well as a shorter 'perf -vv' (Jin Yao)
      
         - Add a "dso_size" sort order (Kim Phillips)
      
         - Remove redundant ')' in the tracepoint output in 'perf trace'
           (Changbin Du)
      
         - Synchronize x86's cpufeatures.h, no effect on toolss (Arnaldo

         - Show group details on the title line in the annotate browser and

           have headers (Arnaldo Carvalho de Melo)
      
         - Fixup vertical line separating metrics from instructions and
           cleaning unused lines at the bottom, both in the annotate TUI
           browser (Arnaldo Carvalho de Melo)
      
         - Remove duplicated 'samples' in lost samples warning in
           'perf report' (Arnaldo Carvalho de Melo)
      
         - Synchronize i915_drm.h, silencing the perf build process,
           automagically adding support for the new DRM_I915_QUERY ioctl
           (Arnaldo Carvalho de Melo)
      
         - Make auxtrace_queues__add_buffer() allocate struct buffer, from a
           patchkit already applied (Adrian Hunter)
      
         - Fix the --stdio2/TUI annotate output to include group details, be
           it for a recorded '{a,b,f}' explicit event group or when forcing
           group display using 'perf report --group' for a set of events not
           recorded as a group (Arnaldo Carvalho de Melo)
      
         - Fix display artifacts in the ui browser (base class for the
           annotate and main report/top TUI browser) related to the extra
           title lines work (Arnaldo Carvalho de Melo)
      
         - perf auxtrace refactorings, leftovers from a previously partially
           processed patchset (Adrian Hunter)
      
         - Fix the builtin clang build (Sandipan Das, Arnaldo Carvalho de
           Melo)
      
         - Synchronize i915_drm.h, silencing a perf build warning and in the
           process automagically adding support for a new ioctl command
           (Arnaldo Carvalho de Melo)
      
         - Fix a strncpy issue in uprobe tracing"
