tools/arch/x86/include/asm/
commit cec07f53c398f22576df77052c4777dc13f14962 upstream.
And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files
introduced by eae7a755ee81 ("perf tools, x86: Build perf on older
user-space as well").
This way we get closer to mirroring the kernel for cases where __NR_
can't be found for some include path/_GNU_SOURCE/whatever scenario.

By adding libbpf into perf's Makefile, this patch enables perf to build
libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set.
The newly introduced code is similar to how libapi and libtraceevent
are wired into Makefile.perf.
MANIFEST is also updated for 'make perf-*-src-pkg'.
Append make_no_libbpf to tools/perf/tests/make.
The 'bpf' feature check is appended into default FEATURE_TESTS and
FEATURE_DISPLAY, so perf will check the API version of bpf in
/path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except
when we are trying to port this code to an old kernel.
Error messages are also updated to notify users about the lack of BPF
support in 'perf record' if libelf is missing or the BPF API check
failed.
tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf
files when working on perf using tools/perf/tags.

The auxtrace code needed by Intel PT uses the __get_cpuid() gcc builtin,
that is not present in old systems, breaking the build.
Add a test to check for that builtin and disable AUXTRACE in those
systems.
[acme@rhel5 linux]$ make NO_LIBPERL=1 -C tools/perf O=/tmp/build/perf install-bin
make: Entering directory `/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j2' parallel build

<SNIP>
... lzma: [ on ]
... get_cpuid: [ OFF ]
<SNIP>
config/Makefile:630: Your gcc lacks the __get_cpuid() builtin, disables support for auxtrace/Intel PT, please install a newer gcc
MKDIR /tmp/build/perf/util/

The existing numa test checks only if numa.h and numa_available() are
present, but that can be satisfied with an old libnuma that is not
enough for the 'perf bench numa' entry, so add a test to check for that:

make: Entering directory `/home/acme/git/linux/tools/perf'

regs_query_register_offset() is a helper function which converts
register name like "%rax" to offset of a register in 'struct pt_regs',
which is required by BPF prologue generator.
PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture
supports converting name of a register to its offset in 'struct
pt_regs'.
HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced as the corresponding
CFLAGS of PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET.

The Fedora 22 version of libdw requires a couple of extra libraries to
link. With a dynamic link the dependencies are pulled in automatically,
but this doesn't work for static linking. Add the needed libraries
explicitely to the feature probe and the Makefile.
v2: Explicitly check for static linking and only add the dependencies
when -static is set. This is to avoid regressions on Arnaldo's system.

When building with a prefix ending with a slash, for example:
$ make prefix=/usr/local/
one of the perf tests fail to compile due to BUILD_STR macro mishandling
bindir_SQ string containing with two slashes:
-DBINDIR="BUILD_STR(/usr/local//bin)"
with the following error:
CC tests/attr.o
tests/attr.c: In function ‘test__attr’:
tests/attr.c:168:50: error: expected ‘)’ before ‘;’ token
snprintf(path_perf, PATH_MAX, "%s/perf", BINDIR);
^
tests/attr.c:176:1: error: expected ‘;’ before ‘}’ token
}
^
tests/attr.c:176:1: error: control reaches end of non-void function [-Werror=return-type]
}
^
cc1: all warnings being treated as errors
This patch works around the problem by "cleaning" the bindir string
using make's abspath function.

Disabling libbabeltrace check by default and replacing the
NO_LIBBABELTRACE make variable with LIBBABELTRACE.
Users wanting the libbabeltrace feature need to build via:
$ make LIBBABELTRACE=1
The reason for this is that the libababeltrace interface we use (version
1.3) hasn't been packaged/released yet, thus the failing feature check
only slows down build and confuses other (non CTF) developers.

We have 2 feature_check functions, which conflict with each other.
Fixing it by renaming the latter to feature_display_check.

Commit:
c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on")
removed the definition of IS_X86_64 but not all places using it, with
the consequence that perf-read-vdsox32 would not be built anymore, and
the default lib install directory was 'lib' instead of 'lib64'.
Also needs to go to v3.19.

It only contains (FEATURE_TESTS - FEATURE_DISPLAY) tests to display the
rest of the checks on 'make VF=1'. But we can actually compute this
list, which is less confusing.
Also renaming LIB_FEATURE_TESTS into FEATURE_DISPLAY, so it reflects
what this variable actually does - display its tests status to user.

Commit b11db6581beaccef8ae9a388ae96074aa5cc144f ("perf tools: Fix build
error on ARCH=i386/x86_64/sparc64") uses sed on ARCH, which triggers a
bug in sequence of sed expression, where 's/arm.*/arm/' will replace
'arm64' to 'arm', causes arm64 building failure.
This patch prevent 'arm64' to be mached for 'arm.*' case.

using the libbabeltrace feature test.

Following patch added -Werror for feature builds:
b49f1a4be701 perf tools: Improve feature test debuggability
and exposed a problem in the libbabeltrace feature build, because it was
including wrong header and gcc couldn't find the used symbol definition.
Adding proper header and keeping the old one as it is needed also
(libbabeltrace quirk).

Certain feature tests fail with link errors:
triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin
gcc -MD -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by
/tmp/cc6dRSqd.o: In function `main':
test-libbabeltrace.c:(.text+0xf): undefined reference to `bt_ctf_stream_class_get_packet_context_type'
although they should already fail with a build error due to lack of a
proper prototype for the function. Due to this I first tried to find
which library was missing - while it was the whole feature that was
missing from the .h file already.
To solve this, propagate -Wall -Werror to all testcases and remove them
from testcase Makefile rules that used them explicitly.
A missing feature now outputs:
triton:~/tip/tools/perf/config/feature-checks> make test-libbabeltrace.bin
gcc -MD -Wall -Werror -o test-libbabeltrace.bin test-libbabeltrace.c # -lbabeltrace provided by
test-libbabeltrace.c: In function ‘main’:

Change the Python detection message from:
config/Makefile:566: No python-config tool was found
config/Makefile:566: Python support will not be built
config/Makefile:565: No 'python-config' tool was found: disables Python support - please install python-devel/python-dev
It's now a standard one-line message with a package install suggestion,
and it also uses the standard language used by other feature detection
messages.

This message:
Makefile:153: The path 'python-config' is not executable.
Appears on every perf build that does not have a sufficient python
environment installed. It's really just an internal detail of python
configuration pass and users should not see it - and it's pretty
meaningless to them in any case because the message is not very helpful.
(So it's not executable. Why does that matter? What can the user do
about it?)
Remove the warning, the missing python feature warning is sufficient:
config/Makefile:566: No python-config tool was found
config/Makefile:566: Python support will not be built
although even that one isn't very helpful to users: so no Python support
will be built, what can the user do to fix that? Most other such
warnings give package install suggestions.

He Kuang reported that current perf tools failed to build when ARCH
variable was given like above.
It was because the name is different that internal directory name. I
can see that David's sparc64 build has same problem.
So fix it by applying the sed conversion script to the command line ARCH
variable also, and fixing the converted name there (i.e. i386/x86_64 ->
x86, sparc64 -> sparc).

Needed to build perf/core buildable in some cases.
