tracing: Add hist trigger support for user-defined sorting ('sort=' param)

Allow users to specify keys and/or values to sort on. With this addition, keys and values specified using the 'keys=' and 'vals=' keywords can be used to sort the hist trigger output via a new 'sort=' keyword. If multiple sort keys are specified, the output will be sorted using the second key as a secondary sort key, etc. The default sort order is ascending; if the user wants a different sort order, '.descending' can be appended to the specific sort key. Before this addition, output was always sorted by 'hitcount' in ascending order. This expands the hist trigger syntax from this: # echo hist:keys=xxx:vals=yyy \ [ if filter] > event/trigger to this: # echo hist:keys=xxx:vals=yyy:sort=zzz.descending \ [ if filter] > event/trigger Link: http://lkml.kernel.org/r/b30a41db66ba486979c4f987aff5fab500ea53b3.1457029949.git.tom.zanussi@linux.intel.com Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com> Tested-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Reviewed-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
