further reduced
damos_quota_goal.py selftest see if DAMOS quota goals tuning feature
increases or reduces the effective size quota for given score as expected.
The tuning feature sets the minimum quota size as one byte, so if the
effective size quota is already one, we cannot expect it further be
reduced. However the test is not aware of the edge case, and fails since
it shown no expected change of the effective quota. Handle the case by
updating the failure logic for no change to see if it was the case, and
simply skips to next test input.

This reverts commit a5c6bc590094a1a73cf6fa3f505e1945d2bf2461.
The general approach described in commit e076eaca5906 ("selftests: break
the dependency upon local header files") was taken one step too far here:
it should not have been extended to include the syscall numbers. This is
because doing so would require per-arch support in tools/include/uapi, and
no such support exists.
This revert fixes two separate reports of test failures, from Dave
Hansen[1], and Li Wang[2]. An excerpt of Dave's report:
Before this commit (a5c6bc590094a1a73cf6fa3f505e1945d2bf2461) things are
fine. But after, I get:

Add extra parameters for rcutorture module. One is the "nfakewriters"
which is set -1. There will be created number of test-kthreads which
correspond to number of CPUs in a test system. Those threads randomly
invoke synchronize_rcu() call.
Apart of that "rcu_normal" is set to 1, because it is specifically for
a normal synchronize_rcu() testing, also a newly added parameter which
is "rcu_normal_wake_from_gp" is set to 1 also. That prevents interaction
with other callbacks in a system.

Commit 14be4e6f3522 ("selftests: vDSO: fix ELF hash table entry size for s390x")
changed the type of the ELF hash table entries to 64bit on s390x.
However the *GNU* hash tables entries are always 32bit.
The "bucket" pointer is shared between both hash algorithms.
On s390, this caused the GNU hash algorithm to access its 32-bit entries as if they
were 64-bit, triggering compiler warnings (assignment between "Elf64_Xword *" and
"Elf64_Word *") and runtime crashes.
Introduce a new dedicated "gnu_bucket" pointer which is used by the GNU hash.

behavior
Fix some related issues (done in a single patch to avoid introducing
intermediate bisect warnings):
1) The SMP version of mwait_play_dead() doesn't return, but its
!SMP counterpart does. Make its calling behavior consistent by
resolving the !SMP version to a BUG(). It should never be called
anyway, this just enforces that at runtime and enables its callers
to be marked as __noreturn.
2) While the SMP definition of mwait_play_dead() is annotated as
__noreturn, the declaration isn't. Nor is it listed in
tools/objtool/noreturns.h. Fix that.
3) Similar to #1, the SMP version of acpi_processor_ffh_play_dead()
doesn't return but its !SMP counterpart does. Make the !SMP
version a BUG(). It should never be called.
4) acpi_processor_ffh_play_dead() doesn't return, but is lacking any
__noreturn annotations. Fix that.
This fixes the following objtool warnings:
vmlinux.o: warning: objtool: acpi_processor_ffh_play_dead+0x67: mwait_play_dead() is missing a __noreturn annotation
vmlinux.o: warning: objtool: acpi_idle_play_dead+0x3c: acpi_processor_ffh_play_dead() is missing a __noreturn annotation

During the initial mprotect(RO) stage of mmu_stress_test, keep vCPUs
spinning until all vCPUs have hit -EFAULT, i.e. until all vCPUs have tried
to write to a read-only page. If a vCPU manages to complete an entire
iteration of the loop without hitting a read-only page, *and* the vCPU
observes mprotect_ro_done before starting a second iteration, then the
vCPU will prematurely fall through to GUEST_SYNC(3) (on x86 and arm64) and
get out of sequence.
Replace the "do-while (!r)" loop around the associated _vcpu_run() with
a single invocation, as barring a KVM bug, the vCPU is guaranteed to hit
-EFAULT, and retrying on success is super confusion, hides KVM bugs, and
complicates this fix. The do-while loop was semi-unintentionally added
specifically to fudge around a KVM x86 bug, and said bug is unhittable
without modifying the test to force x86 down the !(x86||arm64) path.
On x86, if forced emulation is enabled, vcpu_arch_put_guest() may trigger
emulation of the store to memory. Due a (very, very) longstanding bug in
KVM x86's emulator, emulate writes to guest memory that fail during
__kvm_write_guest_page() unconditionally return KVM_EXIT_MMIO. While that
is desirable in the !memslot case, it's wrong in this case as the failure
happens due to __copy_to_user() hitting a read-only page, not an emulated
MMIO region.
But as above, x86 only uses vcpu_arch_put_guest() if the __x86_64__ guards
are clobbered to force x86 down the common path, and of course the
unexpected MMIO is a KVM bug, i.e. *should* cause a test failure.

Pull tracing fixes from Steven Rostedt:
- Fix crash from bad histogram entry
An error path in the histogram creation could leave an entry in a
link list that gets freed. Then when a new entry is added it can
cause a u-a-f bug. This is fixed by restructuring the code so that
the histogram is consistent on failure and everything is cleaned up
appropriately.
- Fix fprobe self test
The fprobe self test relies on no function being attached by ftrace.
BPF programs can attach to functions via ftrace and systemd now does
so. This causes those functions to appear in the enabled_functions
list which holds all functions attached by ftrace. The selftest also
uses that file to see if functions are being connected correctly. It
counts the functions in the file, but if there's already functions in
the file, it fails. Instead, add the number of functions in the file
at the start of the test to all the calculations during the test.
- Fix potential division by zero of the function profiler stddev
The calculated divisor that calculates the standard deviation of the
function times can overflow. If the overflow happens to land on zero,
that can cause a division by zero. Check for zero from the
calculation before doing the division.
TODO: Catch when it ever overflows and report it accordingly. For
now, just prevent the system from crashing.

The fprobe test fails on Fedora 41 since the fprobe test assumption that
the number of enabled_functions is zero before the test starts is not
necessarily true. Some user space tools, like systemd, add BPF programs
that attach to functions. Those will show up in the enabled_functions table
and must be taken into account by the fprobe test.
Therefore count the number of lines of enabled_functions before tests
start, and use that as base when comparing expected results.

Pull sound fixes from Takashi Iwai:
"A collection of fixes. The only slightly large change is for ASoC
Cirrus codec, but that's still in a normal range. All the rest are
small device-specific fixes and should be fairly safe to take"

Introduce __COMPAT_scx_bpf_events() to use scx_bpf_events() in a
compatible way also with kernels that don't provide this kfunc.
This also fixes the following error with scx_qmap when running on a
kernel that does not provide scx_bpf_events():
; scx_bpf_events(&events, sizeof(events)); @ scx_qmap.bpf.c:777
318: (b7) r2 = 72 ; R2_w=72 async_cb
319: <invalid kfunc call>
kfunc 'scx_bpf_events' is referenced but wasn't resolved
Fixes: 9865f31d852a4 ("sched_ext: Add scx_bpf_events() and scx_read_event() for BPF schedulers")

Some drivers, like tg3, do not set combined-count:
$ ethtool -l enp4s0f1
Channel parameters for enp4s0f1:
Pre-set maximums:
RX: 4
TX: 4
Other: n/a
Combined: n/a
Current hardware settings:
RX: 4
TX: 1
Other: n/a
Combined: n/a
In the case where combined-count is not set, the ethtool netlink code
in the kernel elides the value and the code in the test:
netnl.channels_get(...)
With a tg3 device, the returned dictionary looks like:
{'header': {'dev-index': 3, 'dev-name': 'enp4s0f1'},
'rx-max': 4,
'rx-count': 4,
'tx-max': 4,
'tx-count': 1}
Note that the key 'combined-count' is missing. As a result of this
missing key the test raises an exception:
# Exception| if channels['combined-count'] == 0:
# Exception| ~~~~~~~~^^^^^^^^^^^^^^^^^^
# Exception| KeyError: 'combined-count'
Change the test to check if 'combined-count' is a key in the dictionary
first and if not assume that this means the driver has separate RX and
TX queues.
With this change, the test now passes successfully on tg3 and mlx5
(which does have a 'combined-count').
