sort__sym_from_cmp()
Addresses of two data structure members were determined before
corresponding null pointer checks in the implementation of the function
“sort__sym_from_cmp”.
Thus avoid the risk for undefined behaviour by removing extra
initialisations for the local variables “from_l” and “from_r” (also
because they were already reassigned with the same value behind this
pointer check).
This issue was detected by using the Coccinelle software.

Summary from https://github.com/intel/perfmon/pull/68
- Numerous uncore event additions and changes.
- Description updates for core events XQ.FULL_CYCLES and MISC2_RETIRED.LFENCE.
- Update ARITH.IDIV_ACTIVE counter mask.
This change also gets rid of uncore-other as a topic, derived from the
file name, breaking it apart in to more specific topics.

'sched:sched_wakeup'
'perf sched latency' is incorrect to get process schedule latency when
it used 'sched:sched_wakeup' to analysis perf.data.
Because 'perf record' prefers to use 'sched:sched_waking' to
'sched:sched_wakeup' since commit d566a9c2d482 ("perf sched: Prefer
sched_waking event when it exists"). It's very reasonable to evaluate
process schedule latency.
Similarly, update sched latency/map/replay to use sched_waking events.

In __cmd_top(), perf_set_multithreaded() is used to enable
pthread_rwlock, thus down_read() and down_write () are not nops,
handling concurrency problems
Then 'perf top' uses perf_set_singlethreaded(), switching to the single
threaded phase, assuming that no thread concurrency will happen later.
However, a use after free problem could occur in the single threaded
phase, the concurrent procedure is this:
display_thread process_thread
-------------- --------------
thread__comm_len
-> thread__comm_str
-> __thread__comm_str(thread)
thread__delete
-> comm__free
-> comm_str__put
-> zfree(&cs->str)
-> thread->comm_len = strlen(comm);
Since in single thread phase, perf_singlethreaded is true, down_read()
and down_write() do nothing to avoid concurrency problems.
This patch moves the perf_set_singlethreaded() call to the function tail
to expand the multithreaded phase range, making display_thread() and
process_thread() concurrency safe.

This file already used zfree() in other places, so this just plugs some
