This tool allow to set directly the time and date to a RTC device.
Unlike other tools isn't doens't use "struct timeval" or "time_t"
so it is safe for 32bits platforms when testing for y2038/2106 bug.

net has the same issue.
Add support for ntohl and htonl in tools/testing/selftests/bpf/bpf_endian.h.
Also move bpf_helpers.h from samples/bpf to selftests/bpf and change
compiler include logic so that programs in samples/bpf can access the headers
in selftests/bpf, but not the other way around.

We currently fail the MMAP event processing if we don't have the MMAP
event's specific arch unwind support compiled in.
That's wrong and can lead to unresolved mmaps in report output for 32bit
binaries on 64bit server, like in this example on x86_64 server:
$ cat ex.c
int main(int argc, char **argv)
{
while (1) {}
}
$ gcc -o ex -m32 ex.c
$ perf record ./ex
^C[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.371 MB perf.data (9322 samples) ]
Before:
$ perf report --stdio
SNIP
# Overhead Command Shared Object Symbol
# ........ ....... ................ ......................
#
100.00% ex [unknown] [.] 0x00000000080483de
0.00% ex [unknown] [.] 0x00000000f76dba4f
0.00% ex [unknown] [.] 0x00000000f76e4c11
0.00% ex [unknown] [.] 0x00000000f76daa30
After:
$ perf report --stdio
SNIP
# Overhead Command Shared Object Symbol
# ........ ....... ............. ...............
#
100.00% ex ex [.] main
0.00% ex ld-2.24.so [.] _dl_start
0.00% ex ld-2.24.so [.] do_lookup_x
0.00% ex ld-2.24.so [.] _start
The fix is not to fail, just warn if there's not unwind support compiled
in.

We should set attr.exclude_kernel when probing for attr.precise_ip
level, otherwise !CAP_SYS_ADMIN users will not default to skidless
samples in capable hardware.
The increase in the paranoid level in commit 0161028b7c8a ("perf/core:
Change the default paranoia level to 2") broke this, fix it by excluding
kernel samples when probing.
Before:
$ perf record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.018 MB perf.data (6 samples) ]
$ perf evlist -v
cycles:u: sample_freq: 4000, sample_type: IP|TID|TIME|PERIOD, exclude_kernel: 1
After:
$ perf record usleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.018 MB perf.data (8 samples) ]
$ perf evlist -v
cycles:ppp: sample_freq: 4000, sample_type: IP|TID|TIME|PERIOD, exclude_kernel: 1, precise_ip: 3
^^^^^^^^^^^^^
^^^^^^^^^^^^^
^^^^^^^^^^^^^
$
To further clarify: we always set .exclude_kernel when non !CAP_SYS_ADMIN
users profile, its just on the attr.precise_ip probing that we weren't doing
so, fix it.

Pull objtool fix from Thomas Gleixner:
"A fix to the objtool sibling call detection logic to distinguish
normal jumps inside a function from a real sibling call"
* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
objtool: Fix sibling call detection logic

With some configs, objtool reports the following warning:
arch/x86/kernel/ftrace.o: warning: objtool: ftrace_modify_code_direct()+0x2d: sibling call from callable instruction with modified stack frame
The instruction it's complaining about isn't actually a sibling call.
It's just a normal jump to an address inside the function. Objtool
thought it was a sibling call because the instruction's jump_dest wasn't
initialized because the function was supposed to be ignored due to its
use of sync_core().
Objtool ended up validating the function instead of ignoring it because
it didn't properly recognize a sibling call to the function. So fix the
sibling call logic. Also add a warning to catch ignored functions being
validated so we'll get a more useful error message next time.

This allows to detect -s (--silent) option without checking GNU Make
version.
As commit e36aaea28972 ("kbuild: Fix silent builds with make-4")
pointed out, GNU Make 4.x changed the way/order it presents the
command line options into MAKEFLAGS.
In Make 3.8x, 's' is always the first in a group of short options.
The group may be prefixed with '-' in some cases.
In Make 4.x, 's' is always the last in a group of short options.
As commit e6ac89fabd03 ("kbuild: Correctly deal with make options
which contain an 's'") addressed, we also need to deal with long
options that contain 's', like --warn-undefined-variables.
Test cases:
[1] command line input: make --silent
-> MAKEFLAGS for Make 3.8x: s
-> MAKEFLAGS for Make 4.x : s
[2] command line input: make -srR
-> MAKEFLAGS for Make 3.8x: sRr
-> MAKEFLAGS for Make 4.x : rRs
[3] command line input: make -s -rR --warn-undefined-variables
-> MAKEFLAGS for Make 3.8x: --warn-undefined-variables -sRr
-> MAKEFLAGS for Make 4.x : rRs --warn-undefined-variables
My idea to cater to all the cases more easily is to filter out long
options (--%), then search 's' with $(findstring ...). This way will
be more future-proof even if future versions of Make put 's' in the
middle of the group.

Pull Kselftest updates from Shuah Khan:
"This update consists of:
- TAP13 framework and changes to some tests to convert to TAP13.
Converting kselftest output to standard format will help identify
run to run differences and pin point failures easily. TAP13 format
has been in use for several years and the output is human friendly.
Please find the specification:
https://testanything.org/tap-version-13-specification.html
Credit goes to Tim Bird for recommending TAP13 as a suitable
format, and to Grag KH for kick starting the work with help from
Paul Elder and Alice Ferrazzi
The first phase of the TAp13 conversion is included in this update.
Future updates will include updates to rest of the tests.
- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.
- kselftest_harness.h is now available for general use as a result of
Mickaël Salaün's work.
- Several fixes to skip and/or fail tests gracefully on older
releases"

Use ksft_* var arg msg to include strerror() info. in test output. Remove
redundant SKIP/FAIL/PASS logic as it is no longer needed with ksft_ api.
Improve test output to be consistent and clear.

Convert breakpoint_test_arm64 output to TAP13 format. Use ksft_* var arg
msg api to include strerror() info. in the output. Change output from
child process to use ksft_print_msg() instead of ksft_exit_* to avoid
double counting tests and ensure parent process does the test counter
incrementing.

test_execve does rather odd mount manipulations to safely create
temporary setuid and setgid executables that aren't visible to the
rest of the system. Those executables end up in the test's cwd, but
that cwd is MNT_DETACHed.
The core namespace code considers MNT_DETACHed trees to belong to no
mount namespace at all and, in general, MNT_DETACHed trees are only
barely function. This interacted with commit 380cf5ba6b0a ("fs:
Treat foreign mounts as nosuid") to cause all MNT_DETACHed trees to
act as though they're nosuid, breaking the test.
Fix it by just not detaching the tree. It's still in a private
mount namespace and is therefore still invisible to the rest of the
system (except via /proc, and the same nosuid logic will protect all
other programs on the system from believing in test_execve's setuid
bits).
While we're at it, fix some blatant whitespace problems.

In the memory offline test, the $ration was used with RANDOM as the
possibility to get it offlined, correct it to become the portion of
available removable memory blocks.
Also ask the tool to try to offline the next available memory block
if the attempt is unsuccessful. It will only fail if all removable
memory blocks are busy.
A nice example:
$ sudo ./test.sh
Test scope: 10% hotplug memory
online all hot-pluggable memory in offline state:
SKIPPED - no hot-pluggable memory in offline state
offline 10% hot-pluggable memory in online state
trying to offline 3 out of 28 memory block(s):
online->offline memory1
online->offline memory10
./test.sh: line 74: echo: write error: Resource temporarily unavailable
offline_memory_expect_success 10: unexpected fail
online->offline memory100
online->offline memory101

Since older kernel didn't support separated instance of
set_ftrace_filter, if the test case set the filter in
an instance, it will propagate to top-level instance.
This means that the filter setting remains even if we
remove the instance, and will cause other tests failure.
To avoid this issue, reset the ftrace filter if we
detect the propagation.

Current event/toplevel-enable.tc checking the trace
buffer by dumping all events while recording events.
However, this makes system very busy.
To reduce this overhead comes from reading trace buffer
and recording trace buffer, use head instead of cat
and stop tracing while reading.

Skip a part of ftrace filter test related to full-glob
matching if we are sure that the testing kernel is so old
that it does not support full-glob-matching yet.
