So far if we use 'perf record -g' this will make
symbol_conf.use_callchain 'true' and logic will assume that all events
have callchains enabled, but ever since we added the possibility of
setting up callchains for some events (e.g.: -e
cycles/call-graph=dwarf/) while not for others, we limit usage scenarios
by looking at that symbol_conf.use_callchain global boolean, we better
look at each event attributes.
On the road to that we need to look if a hist_entry has callchains, that
is, to go from hist_entry->hists to the evsel that contains it, to then
look at evsel->sample_type for PERF_SAMPLE_CALLCHAIN.
The next step is to add a symbol_conf.ignore_callchains global, to use
in the places where what we really want to know is if callchains should
be ignored, even if present.
Then -g will mean just to select a callchain mode to be applied to all
events not explicitely setting some other callchain mode, i.e. a default
callchain mode, and --no-call-graph will set
symbol_conf.ignore_callchains with that clear intention.
That too will at some point become a per evsel thing, that tools can set
for all or just a few of its evsels.

Its common to have the (evsel->attr.sample_type & PERF_SAMPLE_CALLCHAIN),
so add an evsel__has_callchain(evsel) helper.
This will actually get more uses as we check that instead of
symbol_conf.use_callchain in places where that produces the same result
but makes this decision to be more fine grained, per evsel.

When we have multiple groups in an evlist, say:
$ perf stat -e '{cycles,instructions},{cache-references,cache-misses}' sleep 1
Performance counter stats for 'sleep 1':
343,134 cycles:u
249,292 instructions:u # 0.73 insn per cycle
15,556 cache-references:u
8,925 cache-misses:u # 57.373 % of all cache refs
1.000957550 seconds time elapsed
$
Then the perf_evsel instances for the two group leaders ("cycles" and
"cache-references") will have evsel->nr_members set to 2, while all the
evsel->evlist->nr_entries will be set to 4, so we can't use
evsel->evlist->nr_entries everywhere, as event groups need to be taken
into account.
But this probably requires us to audit at least the forced-group code,
where we want all of the events to be in a "group", to see them all in
the screen, one column for each, even knowing that they were not
necessarily scheduled to count at the same time by the kernel perf
subsystem.

Pull scheduler fixes from Thomas Gleixner:
- two patches addressing the problem that the scheduler allows under
certain conditions user space tasks to be scheduled on CPUs which are
not yet fully booted which causes a few subtle and hard to debug
issue
- add a missing runqueue clock update in the deadline scheduler which
triggers a warning under certain circumstances
- fix a silly typo in the scheduler header file
* 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
sched/headers: Fix typo

2) Pass correct argument to nla_strlcpy() in netfilter, also from Eric
Dumazet.

4) NULL deref in XDP_REDIRECT handling of tun driver, from Toshiaki
Makita.
5) Incorrect idr release in cls_flower, from Paul Blakey.
6) Probe error handling fix in davinci_emac, from Dan Carpenter.
7) Memory leak in XPS configuration, from Alexander Duyck.
8) Use after free with cloned sockets in kcm, from Kirill Tkhai.
9) MTU handling fixes fo ip_tunnel and ip6_tunnel, from Nicolas
Dichtel.

Eve of merge window fix: The original code was so bogus as to be
casting the wrong generic device to an rport and proceeding to take
actions based on the bogus values it found. Fortunately it seems the
location that is dereferenced always exists, so the code hasn't oopsed
yet, but it certainly annoys the memory checkers.
