This patch copies filter.h from include/linux/kernel.h to
tools/include/linux/filter.h to enable other libraries to use macros in it,
like libbpf which will be introduced by further patches.
Currently, the filter.h copy only contains the useful macros needed by
libbpf for not introducing too much dependence.
tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.
One change:
The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
suit user space code generator.

Previous patches introduce llvm__compile_bpf() to compile source file to
eBPF object. This patch adds testcase to test it. It also tests libbpf
by opening generated object after applying next patch which introduces
HAVE_LIBBPF_SUPPORT option.
Since llvm__compile_bpf() prints long messages which users who don't
explicitly test llvm doesn't care, this patch set verbose to -1 to
suppress all debug, warning and error message, and hint user use 'perf
test -v' to see the full output.
For the same reason, if clang is not found in PATH and there's no [llvm]
section in .perfconfig, skip this test.

Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has
no meaning in tools/perf and because we removed the stubs for it, i.e.
we removed the tools/include/linux/export.h file.
This fixes the build for the detached tarball sources cases and removes
one more source of entanglement with the kernel sources.

So that we can remove kernel specific stuff we've been stubbing out via
a tools/include/linux/export.h that gets removed in this patch and to
avoid breakages in the future like the one fixed recently where
rcupdate.h started being used in rbtree.h.

We were using the include/linux/rbtree.h directly from the kernel,
which broke the build as soon as it started using rcupdate.h, to
avoid dragging the rcu header files into tools/, for which there is
no use so far, grab a copy of rbtree.h.
This is the minimal fix, later patches will copy as well lib/rbtree.c
and move rbtree.h into tools/include/, etc.

This patch moves list.h from tools/perf/util/include/linux/list.h to
tools/include/linux/list.h to enable other libraries use macros in it,
like libbpf which will be introduced by further patches. Since list.h
depend on poison.h, poison.h is also moved.
Both file use relative path, so one '..' is removed for each header to
make them suit for new directory.
MANIFEST is also updated for 'make perf-*-src-pkg'.

Adding new build framework into 'tools/build' to be used by tools.
There's no change for actual building at this point, it comes in the
next patches.
The idea and more details are explained in the
'tools/build/Documentation/Build.txt' file.
I adopted everything from the kernel build system, with some changes to
allow for multiple binaries build definitions.
While the kernel's build output is single image (forget modules) we need
to be able to build several binaries/libraries.
The basic idea is that sser provides 'Build' files with objects
definitions like:
perf-y += a.o
perf-y += b.o
libperf-y += c.o
libperf-y += d.o
and the build framework outputs files:
perf-in.o # a.o, b.o compiled in
libperf-in.o # c.o, d.o compiled in

On s390, the vmexit event has a tree-like structure: between
exit_event_begin and exit_event_end several other events may happen and
with each of them refining the previous ones.
This patch adds a decoder for such events to the generic code and also
the files <asm/kvm_perf.h> and kvm-stat.c for s390.
Commands 'perf kvm stat record', 'report' and 'live' are supported.

Currently perf-kvm uses string literals for kvm event names, but it
works only for x86, because other architectures may have other names for
those events.
To reduce dependence on architecture, we add <asm/kvm_perf.h> file with
defines for:
- kvm_entry and kvm_exit events,
- exit reason field name in kvm_exit event,
- length of exit reasons strings,
- vcpu_id field name in kvm trace events,
and replace literals in perf-kvm.

When 553873e1df63 renamed tools/lib/lk to tools/lib/api we forgot to
do the switch in tools/perf/MANIFEST, breaking tarball building:

Eventually this should be useful to other tools/ living utilities.
For now don't try to build any .a, just trying the minimal approach of
separating existing code into multiple .c files that can then be
included wherever they are needed, using whatever build machinery
already in place.

This introduces the tools/lib/lk library, that will gradually have the
routines that now are used in tools/perf/ and other tools and that can
be shared.
Start by carving out debugfs routines for general use.

Add 'perf kvm stat' support to analyze kvm vmexit/mmio/ioport smartly
Usage:
- kvm stat
run a command and gather performance counter statistics, it is the alias of
perf stat
- trace kvm events:
perf kvm stat record, or, if other tracepoints are interesting as well, we
can append the events like this:
perf kvm stat record -e timer:* -a
If many guests are running, we can track the specified guest by using -p or
--pid, -a is used to track events generated by all guests.
- show the result:
perf kvm stat report
The output example is following:
13005
13059
total 2 guests are running on the host
Then, track the guest whose pid is 13059:
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.253 MB perf.data.guest (~11065 samples) ]

The patch series that introduced the top level tools/ makefile and the
libtraceevent broke this feature where files needed to build in a
detached tarball were not included in the MANIFEST file and thus not
included in the tarball.
Fix it by adding the relevant files to the MANIFEST.
