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
