While ppc64le shares the same executable with regular ppc64 the user
variant needs has a dedicated executable.
Introduce a new QEMU_ARCH_USER Makefile variable to accommodate that.

When installing nolibc to a sysroot arch.h is not used so its ABI check
is bypassed. This makes is possible to compile nolibc with a non O32 ABI
which may build but can not run.
Move the check into arch-mips.h so it will always be evaluated.

When an architecture is unsupported arch.h would silently continue.
This leads to a lot of followup errors because my_syscallX() is not

Out of tree builds are much more convenient when building for multiple
architectures or configurations in parallel.
Only absolute O= parameters are supported as Makefile.include will
always resolve relative paths in relation to $(srctree) instead of the
current directory.
Add a call to "make outputmakefile" to verify that the sourcetree is
clean.
This is based on Zhangjins out-of-tree patch.
It extends that work for get_init_cpio support and also drops relative
O= specifications explicitly.

qemu for LoongArch does not work properly with direct kernel boot.
The kernel will panic during initialization and hang without any output.
When booting in EFI mode everything work correctly.
While users most likely don't have the LoongArch EFI binary installed at
least an explicit error about 'file not found' is better than a hanging
test without output that can never succeed.

When TPIDR2 is not supported the tpidr2 ABI test prints the same message
for each skipped test:
ok 1 skipped, TPIDR2 not supported
which isn't ideal for test automation software since it tracks kselftest
results based on the string used to describe the test. This is also not
standard KTAP output, the expected format is:
ok 1 # SKIP default_value
Updated the program to generate this, using the same set of test names that
we would run if the test actually executed.

Patch series "samples: introduce cgroup events listeners", v3.
To begin with, this patch series relocates the cgroup example code to the
samples/cgroup directory, which is the appropriate location for such code
snippets.
Furthermore, a new memcg events listener is introduced. This listener is
a simple yet effective tool for monitoring memory events and managing
counter changes during runtime.
Additionally, as per Andrew Morton's suggestion, a helpful reminder
comment is included in the memcontrol implementation. This comment serves
to ensure that the samples code is updated whenever new events are added.
This patch (of 3):
Move the cgroup_event_listener for cgroup v1 to the samples directory.
This suggestion was proposed by Andrew Morton during the discussion [1].

The PAGEMAP_SCAN ioctl returns information regarding page table entries.
It is more efficient compared to reading pagemap files. CRIU can start to
utilize this ioctl, but it needs info about soft-dirty bits to track
memory changes.
We are aware of a new method for tracking memory changes implemented in
the PAGEMAP_SCAN ioctl. For CRIU, the primary advantage of this method is
its usability by unprivileged users. However, it is not feasible to
transparently replace the soft-dirty tracker with the new one. The main
problem here is userfault descriptors that have to be preserved between
pre-dump iterations. It means criu continues supporting the soft-dirty
method to avoid breakage for current users. The new method will be
implemented as a separate feature.

Adding test that tries to trigger the BUG_IN during early map update
in prog_array_map_poke_run function.
The idea is to share prog array map between thread that constantly
updates it and another one loading a program that uses that prog
array.
Eventually we will hit a place where the program is ok to be updated
(poke->tailcall_target_stable check) but the address is still not
registered in kallsyms, so the bpf_arch_text_poke returns -EINVAL
and cause imbalance for the next tail call update check, which will
fail with -EBUSY in bpf_arch_text_poke as described in previous fix.

A metric is default by having "Default" within its groups. The default
metricgroup name needn't be set and this can result in segv in
default_metricgroup_cmp and perf_stat__print_shadow_stats_metricgroup
that assume it has a value when there is a Default metric group. To
avoid the segv initialize the value to "".
Fixes: 1c0e47956a8e ("perf metrics: Sort the Default metricgroup")

This patch covers the testing of PR_GET_NAME by
reading it's value from proc/self/task/pid/comm
and matching it with the value returned by PR_GET_NAME.
If the values are matched then it's successful, otherwise
it fails.
changes since v1:
- Handled fscanf,fopen error checking.
- Defined MAX_PATH_LEN.

There are a couple of raw printf() calls in vdso_test_abi which result in
non KTAP conforment output such as
[vDSO kselftest] VDSO_VERSION: LINUX_2.6
Convert them to use ksft_print_msg() so that they don't cause confusion for
parsers.

When logging the ID of the currently tested clock vdso_test_clock() puts a
spurious newline at the start of the format string resulting in output
such as
#
clock_id: CLOCK_BOOTTIME
which is a valid but empty KTAP informational message followed by a non
conferment output line. Remove the initial newline to create a more KTAP
friendly
# clock_id: CLOCK_BOOTTIME

The test results from vdso_abi_test are all formatted using a series of
macros:
#define VDSO_TEST_PASS_MSG() "\n%s(): PASS\n", __func__
#define VDSO_TEST_FAIL_MSG(x) "\n%s(): %s FAIL\n", __func__, x
#define VDSO_TEST_SKIP_MSG(x) "\n%s(): SKIP: Could not find %s\n", __func__, x
which don't play nicely with automated KTAP parsers since the actual KTAP
lines are in the form
ok 1
with no test name and we get an additional log line such as
vdso_test_gettimeofday(): PASS
with no preceeding # as KTAP requires. The lack of a test name means that
many automation systems will have a hard time distinguishing between the
different tests or correlating results between runs, the lack of # is less
severe but could potentially cause confusion.
Fix these issues by rewriting all the result reporting to include both the
vDSO function name being tested and (where there is one) the name of the
clock being tested in the main KTAP line. Since we have tests both with and
without a specific clock we abandon the helper macros and just put the
format strings used directly in the ksft_ API calls. When we fail to look
up the relevant vDSO symbol we add a separate print statement explaining
why the skip is being done. This gives output such as:
ok 1 __vdso_gettimeofday
# clock_id: CLOCK_REALTIME
# The time is 1700673118.58091596
ok 2 __vdso_clock_gettime CLOCK_REALTIME
which is much easier for test automation to work with.

This commit addresses compiler warnings in lam.c related to the usage
of non-literal format strings without format arguments in the
'run_test' function.
Warnings fixed:
- Resolved warnings indicating that 'ksft_test_result_skip' and
'ksft_test_result' were called with 't->msg' as a format string without
accompanying format arguments.
Changes made:
- Modified the calls to 'ksft_test_result_skip' and 'ksft_test_result'
to explicitly include a format specifier ("%s") for 't->msg'.
- This ensures that the string is safely treated as a format argument,
adhering to safer coding practices and resolving the compiler warnings.

step_after_suspend_test.c
In the function 'tools/testing/selftests/breakpoints/run_test' within
step_after_suspend_test.c, the ksft_print_msg function call incorrectly
used '$s' as a format specifier. This commit corrects this typo to use the
proper '%s' format specifier, ensuring the error message from
waitpid() is correctly displayed.
The issue manifested as a compilation warning (too many arguments
for format [-Wformat-extra-args]), potentially obscuring actual
runtime errors and complicating debugging processes.
This fix enhances the clarity of error messages during test failures
and ensures compliance with standard C format string conventions.
