The bpf map sockmap supports adding programs via attach commands. This
patch adds the detach command to keep the API symmetric and allow
users to remove previously added programs. Otherwise the user would
have to delete the map and re-add it to get in this state.
This also adds a series of additional tests to capture detach operation
and also attaching/detaching invalid prog types.
API note: socks will run (or not run) programs depending on the state
of the map at the time the sock is added. We do not for example walk
the map and remove programs from previously attached socks.

KCMP's KCMP_EPOLL_TFD mode merged in commit 0791e3644e5ef2 ("kcmp: add
KCMP_EPOLL_TFD mode to compare epoll target files") we've had no selftest
for it yet (except in criu development list). Thus add it.

Pull kselftest updates from Shuah Khan:
- TAP13 framework API and converting tests to TAP13 continues. A few
more tests are converted and kselftest common RUN_TESTS in lib.mk is
enhanced to print TAP13 to cover test shell scripts that won't be
able to use kselftest API.
- Several fixes to existing tests to not fail in unsupported cases.
This has been an ongoing work based on the feedback from stable
release kselftest users.
- A new watchdog test and much needed cleanups to the existing tests
from Eugeniu Rosca.
- Changes to kselftest common lib.mk framework to make RUN_TESTS a
function to be called from individual test make files to run stress
and destructive sub-tests.

When a test process is not able to write to TH_LOG_STREAM, this step
mechanism enable to print the assert number which triggered the failure.
This can be enabled by setting _metadata->no_print to true at the
beginning of the test sequence.
Update the seccomp-bpf test to return 0 if a test succeeded.
This feature is needed for the Landlock tests.

Change common RUN_TESTS to print messages in user friendly TAP13 format.
This change add TAP13 header at the start of RUN_TESTS target run, and
prints the resulting pass/fail messages with test number information in
the TAP 13 format for each test in the run tests list.
This change covers test scripts as well as test programs. Test programs
have an option to use ksft_ API, however test scripts won't be able to.
With this change, test scripts can print TAP13 format output without any
changes to individual scripts.
Test programs can provide TAP13 format output as needed as some tests
already do. Tests that haven't been converted will benefit from this
change. Tests that are converted benefit from the test counts for all
the tests in each test directory.
Running firmware tests:
make --silent -C tools/testing/selftests/firmware/ run_tests
Before the change:

Change lib.mk RUN_TESTS to take test list as an argument. This will
allow it to be called from individual test makefiles to run additional
tests that aren't suitable for a default kselftest run. As an example,
timers test includes destructive tests that aren't included in the
common run_tests target.
Change times/Makefile to use RUN_TESTS call with destructive test list
as an argument instead of using its own RUN_TESTS target.

When a test is skipped, instead of using a special exit code of 4, treat
it as pass condition and use exit code of 0. It makes sense to treat skip
as pass since the test couldn't be run as opposed to a failed test.

Change default arguments for leap-a-day to always set the time
each iteration (rather then waiting for midnight UTC), and to
only run 10 interations (rather then infinite).
If one wants to wait for midnight UTC, they can use the new -w
flag, and we add a note to the argument help that -i -1 will
run infinitely.

The rtc-generic and opal-rtc are failing to run this test as they do not
support all the features. Let's treat the error returns and skip to the
following test.
Theoretically the test_DATE should be also adjusted, but as it's enabled
on demand I think it makes sense to fail in such case.

Add 3-level verbosity for showing traced command log
on console immediately. Since some test cases can cause
kernel pacic if there is a probrem (like regression etc.),
we can not know which command caused the problem without
traced command log. This verbosity (-vvv) solves that
because it shows the log on console immediately. User
can get continuous command/error log.
Note that this is a kind of kernel debug mode, if you
don't see any kernel related issue, you don't need this
verbosity.

Do not return failure exit code (1) for unsupported testcases,
since it is expected for stable kernels.
Previously, ftracetest is expected to run only on current
release for avoiding regressions. However, nowadays we run
it on stable kernels. This means some test cases must return
unsupported result. In such case, we should NOT exit
ftracetest with error status for unsupported results so that
kselftest (upper tests wrapper) shows it passed correctly.
Note that we continue to treat unresolved results as failure,
if test writers would like to notice user that the test result
should be reviewed, they can use exit_unresolved.

Some watchdog drivers implement WDIOF_CARDRESET feature. As example,
see commit b6ef36d2c1e3 ("watchdog: qcom: Report reboot reason").
This option allows reporting to userspace the cause of the last boot
(POR/watchdog reset), being helpful in e.g. automated test-cases.
Add support for WDIOC_GETBOOTSTATUS in the test code, to be able to:
- check if watchdog drivers properly implement WDIOF_CARDRESET.
- check the last boot status, if WDIOF_CARDRESET is implemented.
Make the `-b, --bootstatus` option one-shot. That means, skip the
keepalive mechanism if `-b` is provided on the command line, as we
are only interested in the boot status information.
Tested on Rcar-H3 Salvator-X board:
********************** Cold boot finished
salvator-x:/home/root# ./watchdog-test -h
Usage: ./watchdog-test [options]
-b, --bootstatus Get last boot status (Watchdog/POR)
-d, --disable Turn off the watchdog timer
-e, --enable Turn on the watchdog timer
-h, --help Print the help message
-p, --pingrate=P Set ping rate to P seconds (default 1)
-t, --timeout=T Set timeout to T seconds
Parameters are parsed left-to-right in real-time.
Example: ./watchdog-test -d -t 10 -p 5 -e
salvator-x:/home/root#
salvator-x:/home/root# ./watchdog-test -b
Last boot is caused by: Power-On-Reset.
salvator-x:/home/root#
salvator-x:/home/root# ./watchdog-test -d -t 1 -p 2 -e
Watchdog card disabled.
Watchdog timeout set to 1 seconds.
Watchdog ping rate set to 2 seconds.
Watchdog card enabled.
Watchdog Ticking Away!
********************** Reboot due to watchdog trigger finished
salvator-x:/home/root# ./watchdog-test -b
Last boot is caused by: Watchdog.
salvator-x:/home/root#
salvator-x:/home/root# reboot
********************** Reboot due to user action finished

Switch from manual argv[] parsing to getopt_long() argument processing.
This creates more readable code and allows easier feature addition.
This also fixes some segmentation faults introduced by
commit 1dbdcc810928 ("selftests: watchdog: accept multiple params on
command line"), when options -t or -p are not given the required value:
./watchdog-test -p 1 -t
./watchdog-test -t 1 -p
No changes are intended in the way watchdog-test interacts with the
kernel. The only noticible changes, tightly related to the addition
of getopt (and done for easier maintenance), are:
- help message has been reworked and migrated to a dedicated function.
- all short/long options and the help message are sorted alphabetically.
- all case statements inside the getopt loop are sorted alphabetically.

Pull powerpc updates from Michael Ellerman:
"Nothing really major this release, despite quite a lot of activity.
Just lots of things all over the place.
Some things of note include:
- Access via perf to a new type of PMU (IMC) on Power9, which can
count both core events as well as nest unit events (Memory
controller etc).
- Optimisations to the radix MMU TLB flushing, mostly to avoid
unnecessary Page Walk Cache (PWC) flushes when the structure of the
tree is not changing.
- Reworks/cleanups of do_page_fault() to modernise it and bring it
closer to other architectures where possible.
- Rework of our page table walking so that THP updates only need to
send IPIs to CPUs where the affected mm has run, rather than all
CPUs.
- The size of our vmalloc area is increased to 56T on 64-bit hash MMU
systems. This avoids problems with the percpu allocator on systems
with very sparse NUMA layouts.
- STRICT_KERNEL_RWX support on PPC32.
- A new sched domain topology for Power9, to capture the fact that
pairs of cores may share an L2 cache.
- Power9 support for VAS, which is a new mechanism for accessing
coprocessors, and initial support for using it with the NX
compression accelerator.
- Major work on the instruction emulation support, adding support for
many new instructions, and reworking it so it can be used to
implement the emulation needed to fixup alignment faults.
- Support for guests under PowerVM to use the Power9 XIVE interrupt
controller.
And probably that many things again that are almost as interesting,
but I had to keep the list short. Plus the usual fixes and cleanups as
always.

Currently these tests won't build with a `--enable-default-pie`
compiler as they require r30 to be clobbered. This gives
an error:
ptrace-tm-spd-gpr.c:41:2: error: PIC register clobbered by 'r30' in 'asm'
This forces these tests to be built no-pie.
