    …ub/scm/linux/kernel/git/acme/linux
    
    Pull more perf tools updates from Arnaldo Carvalho de Melo:
    
     - Add missing fields and remove some duplicate fields when printing a
       perf_event_attr.
    
     - Fix hybrid config terms list corruption.
    
     - Update kernel header copies, some resulted in new kernel features
       being automagically added to 'perf trace' syscall/tracepoint argument
       id->string translators.
    
     - Add a file generated during the documentation build to .gitignore.
    
     - Add an option to build without libbfd, as some distros, like Debian
       consider its ABI unstable.
    
     - Add support to print a textual representation of IBS raw sample data
       in 'perf report'.
    
     - Fix bpf 'perf test' sample mismatch reporting
    
     - Fix passing arguments to stackcollapse report in a 'perf script'
       python script.
    
     - Allow build-id with trailing zeros.
    
     - Look for ImageBase in PE file to compute .text offset.

  9. perf tools: Allow build-id with trailing zeros

    Currently perf saves a build-id with size but old versions assumes the
    size of 20.  In case the build-id is less than 20 (like for MD5), it'd
    fill the rest with 0s.
    
    I saw a problem when old version of perf record saved a binary in the
    build-id cache and new version of perf reads the data.  The symbols
    should be read from the build-id cache (as the path no longer has the
    same binary) but it failed due to mismatch in the build-id.

  10. perf tools: Fix hybrid config terms list corruption

    A config terms list was spliced twice, resulting in a never-ending loop
    when the list was traversed. Fix by using list_splice_init() and copying
    and freeing the lists as necessary.
    
    This patch also depends on patch "perf tools: Factor out
    copy_config_terms() and free_config_terms()"
    
    Example on ADL:
