      Some architectures define their own arch_test_bit and they also need
      arch_test_bit_acquire, otherwise they won't compile.  We also clean up
      the code by using the generic test_bit if that is equivalent to the
      arch-specific version.

      perf record: Fix manpage formatting of description of support to hybrid systems · e89eaa61
      Andi Kleen authored
      
      
      The Intel hybrid description is written in a different style than the
      rest of the perf record man page. There were some new command line
      options added after it which resulted in very strange section ordering.
      Move the hybrid include last.
      
      Also the sub sections in the hybrid document don't fit the record
      manpage well (especially since it talks about all kinds of unrelated
      commands). I left this for now, but would be better to separate this
      properly in the different man pages.
      
      It would be better to use sub sections for the other sections, but these
      don't seem to be supported in AsciiDoc?
      
      Some of the examples are still misrendered in the manpage with an
      indented troff command, but I don't know how to fix that.
      
      In any case it's now better than before.
