perf tools: Apply correct label to user/kernel symbols in branch mode
In branch mode, the branch symbols were being displayed with incorrect cpumode labels. So fix this. For example, before: # perf record -b -a -- sleep 1 # perf report -b Overhead Command Source Shared Object Source Symbol Target Symbol 0.08% swapper [kernel.kallsyms] [k] rcu_idle_enter [k] cpuidle_enter_state ==> 0.08% cmd0 [kernel.kallsyms] [.] psi_group_change [.] psi_group_change 0.08% cmd1 [kernel.kallsyms] [k] psi_group_change [k] psi_group_change After: # perf report -b Overhead Command Source Shared Object Source Symbol Target Symbol 0.08% swapper [kernel.kallsyms] [k] rcu_idle_enter [k] cpuidle_enter_state 0.08% cmd0 [kernel.kallsyms] [k] psi_group_change [k] pei_group_change 0.08% cmd1 [kernel.kallsyms] [k] psi_group_change [k] psi_group_change Reviewed-by: James Clark <james.clark@arm.com> Signed-off-by: German Gomez <german.gomez@arm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20220126105927.3411216-1-german.gomez@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
