      perf symbols: Record the reason for filtering an address_location · b3cef7f6
      Namhyung Kim authored
      By turning the addr_location->filtered member from a boolean to a u8
      bitmap, reusing (and extending) the hist_filter enum for that.
      
      This patch doesn't change the logic at all, as it keeps the meaning of
      al->filtered !0 to mean that the entry _was_ filtered, so no change in
      how this value is interpreted needs to be done at this point.
      
      This will be soon used in upcoming patches.

      perf timechart: Fix off-by-one error in 'record' argv handling · 263f89bf
      Ramkumar Ramachandra authored
      Since 367b3152 (perf timechart: Add support for -P and -T in timechart
      recording, 2013-11-01), the 'perf timechart record' command stopped
      working:
      
        $ perf timechart record -- git status
        Workload failed: No such file or directory
      
      This happens because of an off-by-one error while preparing the argv for
      cmd_record(): it attempts to execute the command 'status' and complains
      that it doesn't exist. Fix this error.
