The event group feature links relevant hist entries among events so that
they can be displayed together. During the link process, each hist
entry in non-leader events is connected to a hist entry in the leader
event. This is done in order of events specified in the command line so
it assumes that events are linked in the order.
But 'perf top' can break the assumption since it does the link process
multiple times. For example, a hist entry can be in the third event
only at first so it's linked after the leader. Some time later, second
event has a hist entry for it and it'll be linked after the entry of the
third event.
This makes the code compilicated to deal with such unordered entries.
This patch simply unlink all the entries after it's printed so that they
can assume the correct order after the repeated link process. Also it'd
be easy to deal with decaying old entries IMHO.

Currently perf top only decays entries in a selected evsel. I don't
know whether it's intended (maybe due to performance reason?) but anyway
it might show incorrect output when event group is used since users will
see leader event is decayed but others are not.
This patch moves the decay code into perf_top__resort_hists() so that
stdio and TUI code shared the logic.

It was put in place just to make sure the 'new' C++ operator wouldn't
clash with some argument name in util.h, but there is not anymore any

was to get the __maybe_unused definition, that is in linux/compiler.h,
so use that instead and nuke util-cxx.h.

when checking kptr_restrict. Make perf do the same.
Also, the kernel is a more restrictive than "no restrictions" in case of
kptr_restrict==0, so add the same logic to perf.

Following the patch 'perf stat: Fix --no-scale', an alignment trap
happens in process_counter_values() on ARMv7 platforms due to the
attempt to copy non 64 bits aligned double words (pointed by 'count')
via a NEON vectored instruction ('vld1' with 64 bits alignment
constraint).
This patch sets a 64 bits alignment constraint on 'contents[]' field in
'struct xyarray' since the 'count' pointer used above points to such a
structure.

There we need just some struct forward declarations, do that instead and
add the includes needed by metricgroup.c.
That should help with needless rebuilds when changing the removed
headers from metricgroup.h.

Switch the rest of the perf code to use libperf's perf_cpu_map__nr(),
which is the same as current cpu_map__nr() and remove the cpu_map__nr()
function.

The problem is that we don't use SRCARCH (the sanitized ARCH version)

Sometimes we want just to print a message on the center of the screen,
like in 'perf top' while we wait for the minimum amount of samples to be
collected before sorting and showing them.
Also expose __ui__info_window() as an optimization for cases where such
message is to be printed while holding the ui lock.

The next cset will grap const.h copies from the kernel to keep bits.h
in sync as it started to use linux/const.h, that in turn includes
uapi/linux/const.h.
So now we have a file with the same name in tools/include and
tools/uapi/include, and one includes the other, we need to have
tools/include/uapi/ after tools/include/ for this to work, fix it.

Commit e5adfc3e7e ("perf map: Synthesize maps only for thread group
leader") changed the recording side so that we no longer get mmap events
for threads other than the thread group leader (when synthesising these
events for threads which exist before perf is started).
When a file recorded after this change is loaded, the lack of mmap
records mean that unwinding is not set up for any other threads.
This can be seen in a simple record/report scenario:
perf record --call-graph=dwarf -t $TID
perf report
If $TID is a process ID then the report will show call graphs, but if
$TID is a secondary thread the output is as if --call-graph=none was
specified.
Following the rationale in that commit, move the libunwind fields into
struct map_groups and update the libunwind functions to take this
instead of the struct thread. This is only required for
unwind__finish_access which must now be called from map_groups__delete
and the others are changed for symmetry.
Note that unwind__get_entries keeps the thread argument since it is
required for symbol lookup and the libdw unwind provider uses the thread
ID.
