This can happen if a testing node doesn't have RTC (real time clock)
hardware or it doesn't support alarms.
Fixes: 61c57676035d ("selftests/timens: Add Time Namespace test for supported clocks")

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx
Pull SPDX updates from Greg KH:
"Here are three SPDX patches for 5.7-rc1.
One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.
Nothing too complex, but you will get a merge conflict with your
current tree, that should be trivial to handle (one file modified by
two things, one file deleted.)
All three of these have been in linux-next for a while, with no
reported issues other than the merge conflict"

Pull kselftest update from Shuah Khan:
"This kselftest update consists of:
- resctrl_tests for resctrl file system. resctrl isn't included in
the default TARGETS list in kselftest Makefile. It can be run
manually.
- Kselftest harness improvements.
- Kselftest framework and individual test fixes to support runs on
Kernel CI rings and other environments that use relocatable build
and install features.
- Minor cleanups and typo fixes"

While building selftests, the following errors were observed:
> tools/testing/selftests/timens'
> gcc -Wall -Werror -pthread -lrt -ldl timens.c -o tools/testing/selftests/timens/timens
> /usr/bin/ld: /tmp/ccGy5CST.o: in function `check_config_posix_timers':

> collect2: error: ld returned 1 exit status
Quoting commit 870f193d48c2 ("selftests: net: use LDLIBS instead of
LDFLAGS"):
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.
While at here, correct other selftests, not only timens ones.

A test to check that all supported clocks work on host and inside
a new time namespace. Use both ways to get time: through VDSO and
by entering the kernel with implicit syscall.
Introduce a new timens directory in selftests framework for
the next timens tests.
