Change from v5: - change config name to the proper one, CONFIG_BINDER_TRANSACTION_LATENCY_TRACKING. - change tracepoint name to more descriptive one, trace_binder_txn_latency_(alloc|info|free) - enhance some lock protection.
Change from v4: - split up into patch series.
Change from v3: - use tracepoints for binder_update_info and print_binder_transaction_ext, instead of custom registration functions.
Change from v2: - create transaction latency module to monitor slow transaction.
Change from v1: - first patchset.
