Naresh Kamboju reported, that on the i386 build pr_err()
doesn't get defined properly due to header ordering:
perf-in.o: In function `libunwind__x86_reg_id':

Change the definition of the RBCOMPUTE function. The propagate callback
repeatedly calls RBCOMPUTE as it moves from leaf to root. it wants to
stop recomputing once the augmented subtree information doesn't change.
This was previously checked using the == operator, but that only works
when the augmented subtree information is a scalar field. This commit
modifies the RBCOMPUTE function so that it now sets the augmented subtree
information instead of returning it, and returns a boolean value
indicating if the propagate callback should stop.
The motivation for this change is that I want to introduce augmented
rbtree uses where the augmented data for the subtree is a struct instead
of a scalar.

Add RB_DECLARE_CALLBACKS_MAX, which generates augmented rbtree callbacks
for the case where the augmented value is a scalar whose definition
follows a max(f(node)) pattern. This actually covers all present uses of
RB_DECLARE_CALLBACKS, and saves some (source) code duplication in the
various RBCOMPUTE function definitions.

Patch series "make RB_DECLARE_CALLBACKS more generic", v3.
These changes are intended to make the RB_DECLARE_CALLBACKS macro more
generic (allowing the aubmented subtree information to be a struct instead
of a scalar).
I have verified the compiled lib/interval_tree.o and mm/mmap.o files to
check that they didn't change. This held as expected for interval_tree.o;
mmap.o did have some changes which could be reverted by marking
__vma_link_rb as noinline. I did not add such a change to the patchset; I
felt it was reasonable enough to leave the inlining decision up to the
compiler.
This patch (of 3):
Add a short comment summarizing the arguments to RB_DECLARE_CALLBACKS.
The arguments are also now capitalized. This copies the style of the
INTERVAL_TREE_DEFINE macro.
No functional changes in this commit, only comments and capitalization.

As was already noted in rbtree.h, the logic to cache rb_first (or
rb_last) can easily be implemented externally to the core rbtree api.
This commit takes the changes applied to the include/linux/ and lib/
rbtree files in 9f973cb38088 ("lib/rbtree: avoid generating code twice
for the cached versions"), and applies these to the
tools/include/linux/ and tools/lib/ files as well to keep them
synchronized.

They go on accumulating there like the debug.h one, that was introduced
here:
f23610245c1a ("perf list: Add debug support for outputing alias string")
But then, when that need is removed via:
2073ad3326b7 ("perf tools: Factor out PMU matching in parser")
The thing stays there, so continue the house cleaning spree...
list.h not needed, no macros from there are used, and 'struct
list_head' is in linux/types.h, ditto for util.h, no need for that as
well.

With Java 11 there is no seperate JRE anymore.
Details:
https://coderanch.com/t/701603/java/JRE-JDK
Therefore the detection of the JRE needs to be adapted.
This change works for s390 and x86. I have not tested other platforms.

I'm not fully sure if this is the correct fix, but without this I get
crashes on more complex perf stat metric usages. The problem is that
part of the state gets freed when a weak group fails, but then is later
still used. Just don't free the ids, we're going to reuse them anyways
on the weak group retry.
For example:
% perf stat -M IpB,IpCall,IpTB,IPC,Retiring_SMT,Frontend_Bound_SMT,Kernel_Utilization,CPU_Utilization --metric-only -a -I 1000 sleep 2
crashes and gives in valgrind:

Make sure to not free the name passed in by the caller, but free all the
allocated ids when parsing expressions.
The loop at the end knows that the first entry shouldn't be freed, so
make sure the caller name is the first entry.

Ditch it, noone is using it, one more stdio.h include in a hot header.
Fix the fallout in parse-events.y, where we end up using a FILE pointer,
I think due to YYDEBUG being set and in some places, like Amazon Linux 1
we don't get stdio.h included by luck, like in most other places, add a
explicit stdio.h include directive.

We already had evsel_fprintf.c, add its counterpart, so that we can
reduce evsel.h a bit more.
We needed a new perf_event_attr_fprintf.c file so as to have a separate
object to link with the python binding in tools/perf/util/python-ext-sources
and not drag symbol_conf, etc into the python binding.

The sys/types.h header looks more sensible, from its name we can gather
it should be there because of some needed typedef, and it is much
smaller than unistd.h, so use it and fix up the fallout in places where
it was being used for something else entirely but being obtained by
sheer luck, indirectly.

That was done just to have users of writen() and readn(), that before
had their prototypes in util/util.h to get it without having to add an
include for internal/lib.h, but the right way is to add it and by now
all places already do it.
Fix a fallout were readlink() was used but unistd.h was being obtained
by luck thru util.h -> internal/lib.h, now to check why unistd.h is
being included there...

We need the 'page_size' variable in libperf, so move it there.
Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.
Committer notes:
Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.
