Add coverage of the hwcaps for the 2024 dpISA extensions to the hwcap
test.
We don't actually test SIGILL generation for CMPBR since the need to
branch makes it a pain to generate and the SIGILL detection would be
unreliable anyway. Since this should be very unusual we provide a stub
function rather than supporting a missing test.
The sigill functions aren't well sorted in the file so the ordering is a
bit random.

Test a more realistic usage pattern, and one with heavy contention, in order to
actually exercise ntsync's internal synchronization.
This test has several threads in a tight loop acquiring a mutex, modifying some
shared data, and then releasing the mutex. At the end we check if the data is
consistent.

Wine has tests for its synchronization primitives, but these are more accessible
to kernel developers, and also allow us to test some edge cases that Wine does
not care about.
This patch adds tests for semaphore-specific ioctls NTSYNC_IOC_SEM_POST and
NTSYNC_IOC_SEM_READ, and waiting on semaphores.

The selftest runner currently allows selecting tests via the -t
option. This patch adds a new -l option that lists all available tests,
providing users with an overview of the tests they can choose from. This
enhancement is especially useful for scripting and automation purposes,
making it easier to discover and run tests.

Currently, when we run the BPF selftests with the following command:
make -C tools/testing/selftests TARGETS=bpf SKIP_TARGETS=""
The command generates untracked files and directories with make version
less than 4.4:
'''
Untracked files:
(use "git add <file>..." to include in what will be committed)
tools/testing/selftests/bpfFEATURE-DUMP.selftests
tools/testing/selftests/bpffeature/
'''
We lost slash after word "bpf". The reason is slash appending code is as
follow:
'''
OUTPUT := $(OUTPUT)/
$(eval include ../../../build/Makefile.feature)
OUTPUT := $(patsubst %/,%,$(OUTPUT))
'''
This way of assigning values to OUTPUT will never be effective for the
variable OUTPUT provided via the command argument [1] and BPF makefile
is called from parent Makfile(tools/testing/selftests/Makefile) like:
'''
all:
...
$(MAKE) OUTPUT=$$BUILD_TARGET -C $$TARGET
'''
According to GNU make, we can use override Directive to fix this issue [2].

Constify the following API:
struct device *device_find_child(struct device *dev, void *data,
int (*match)(struct device *dev, void *data));
To :
struct device *device_find_child(struct device *dev, const void *data,
device_match_t match);
typedef int (*device_match_t)(struct device *dev, const void *data);
with the following reasons:
- Protect caller's match data @*data which is for comparison and lookup
and the API does not actually need to modify @*data.
- Make the API's parameters (@match)() and @data have the same type as
all of other device finding APIs (bus|class|driver)_find_device().
- All kinds of existing device match functions can be directly taken
as the API's argument, they were exported by driver core.
Constify the API and adapt for various existing usages.
BTW, various subsystem changes are squashed into this commit to meet
'git bisect' requirement, and this commit has the minimal and simplest
changes to complement squashing shortcoming, and that may bring extra
code improvement.

In cxl_dvsec_rr_decode() the pci driver expects to retrieve a cxlds,
struct cxl_dev_state, from the driver_data field of struct device.
While that works for Type 3, drivers for Type 1/2 devices may not
put a cxlds in the driver_data field.
In preparation for supporting Type 1/2 devices, replace parameter
'struct device' with 'struct cxl_dev_state' in cxl_dvsec_rr_decode().
Remove the unused parameter 'cxl_port' in cxl_dvsec_rr_decode().

Commit 82c1f13de3 ("selftests/bpf: Add more stats into veristat")
introduced new stats, added by default in the CSV output, that were not
added to parse_stat_value, used in parse_stats_csv which is used in
comparison mode. Thus it broke comparison mode altogether making it fail
with "Unrecognized stat #7" and EINVAL.
One quirk is that PROG_TYPE and ATTACH_TYPE have been transformed to
strings using libbpf_bpf_prog_type_str and libbpf_bpf_attach_type_str
respectively. Since we might not want to compare those string values, we
just skip the parsing in this patch. We might want to translate it back
to the enum value or compare the string value directly.

The dsp_local_on selftest expects the scheduler to fail by trying to
schedule an e.g. CPU-affine task to the wrong CPU. However, this isn't
guaranteed to happen in the 1 second window that the test is running.
Besides, it's odd to have this particular exception path tested when there
are no other tests that verify that the interface is working at all - e.g.
the test would pass if dsp_local_on interface is completely broken and fails
on any attempt.
Flip the test so that it verifies that the feature works. While at it, fix a
typo in the info message.
