tracepoint: simplification for tracepoints using RCU
Impact: simplify implementation Now, unused memory is handled by struct tp_probes. old code use these three field to handle unused memory. struct tracepoint_entry { ... struct rcu_head rcu; void *oldptr; unsigned char rcu_pending:1; ... }; in this way, unused memory is handled by struct tracepoint_entry. it bring reenter bug(it was fixed) and tracepoint.c is filled full of ".*rcu.*" code statements. this patch removes all these. and: rcu_barrier_sched() is removed. Do not need regain tracepoints_mutex after tracepoint_update_probes() several little cleanup.
