0ef7ef4227 ext4: add missing down_write_data_sem in mext_move_extent().
Commit 962e8a01ea ("ext4: introduce mext_move_extent()") attempts to
call ext4_swap_extents() on the failure path to recover the swapped
extents, but fails to acquire locks for the two inode->i_data_sem,
triggering the BUG_ON statement in ext4_swap_extents().

This issue can be fixed by calling ext4_double_down_write_data_sem()
before ext4_swap_extents().

cd16edba1c ext4: fix ext4_tune_sb_params padding
The padding at the end of struct ext4_tune_sb_params is architecture
specific and in particular is different between x86-32 and x86-64,
since the __u64 member only enforces struct alignment on the latter.

This shows up as a new warning when test-building the headers with
-Wpadded:

include/linux/ext4.h:144:1: error: padding struct size to alignment boundary with 4 bytes [-Werror=padded]

All members inside the structure are naturally aligned, so the only
difference here is the amount of padding at the end. Make the padding
explicit, to have a consistent sizeof(struct ext4_tune_sb_params) of
232 on all architectures and avoid adding compat ioctl handling for
EXT4_IOC_GET_TUNE_SB_PARAM/EXT4_IOC_SET_TUNE_SB_PARAM.

This is an ABI break on x86-32 but hopefully this can go into 6.18.y early
enough as a fixup so no actual users will be affected.  Alternatively, the
kernel could handle the ioctl commands for both sizes (232 and 228 bytes)
on all architectures.

d9b40d7262 selftests/x86: Add selftests include path for kselftest.h after centralization
The previous change centralizing kselftest.h include path in lib.mk caused x86
selftests to fail, as x86 Makefile overwrites CFLAGS using ":=", dropping the
include path added in lib.mk. Therefore, helpers.h could not find kselftest.h
during compilation.

Fix this by adding the tools/testing/sefltest to CFLAGS in x86 Makefile.

762cf75bec LoongArch: dts: Describe PCI sideband IRQ through interrupt-extended
SoC integrated peripherals on LS2K1000 and LS2K2000 could be discovered
as PCI devices, but require sideband interrupts to function, which are
previously described by interrupts and interrupt-parent properties.

However, pci/pci-device.yaml allows interrupts property to only specify
PCI INTx interrupts, not sideband ones. Convert these devices to use
interrupt-extended property, which describes sideband interrupts used by
PCI devices since dt-schema commit e6ea659d2baa ("schemas: pci-device:
Allow interrupts-extended for sideband interrupts"), eliminating
dtbs_check warnings.

a91f86e270 LoongArch: Fix PMU counter allocation for mixed-type event groups
When validating a perf event group, validate_group() unconditionally
attempts to allocate hardware PMU counters for the leader, sibling
events and the new event being added.

This is incorrect for mixed-type groups. If a PERF_TYPE_SOFTWARE event
is part of the group, the current code still tries to allocate a hardware
PMU counter for it, which can wrongly consume hardware PMU resources and
cause spurious allocation failures.

Fix this by only allocating PMU counters for hardware events during group
validation, and skipping software events.

A trimmed down reproducer is as simple as this:

  #include <stdio.h>
  #include <assert.h>
  #include <unistd.h>
  #include <string.h>
  #include <sys/syscall.h>
  #include <linux/perf_event.h>

  int main (int argc, char *argv[])
  {
  	struct perf_event_attr attr = { 0 };
  	int fds[5];

  	attr.disabled = 1;
  	attr.exclude_kernel = 1;
  	attr.exclude_hv = 1;
  	attr.read_format = PERF_FORMAT_TOTAL_TIME_ENABLED |
  		PERF_FORMAT_TOTAL_TIME_RUNNING | PERF_FORMAT_ID | PERF_FORMAT_GROUP;
  	attr.size = sizeof (attr);

  	attr.type = PERF_TYPE_SOFTWARE;
  	attr.config = PERF_COUNT_SW_DUMMY;
  	fds[0] = syscall (SYS_perf_event_open, &attr, 0, -1, -1, 0);
  	assert (fds[0] >= 0);

  	attr.type = PERF_TYPE_HARDWARE;
  	attr.config = PERF_COUNT_HW_CPU_CYCLES;
  	fds[1] = syscall (SYS_perf_event_open, &attr, 0, -1, fds[0], 0);
  	assert (fds[1] >= 0);

  	attr.type = PERF_TYPE_HARDWARE;
  	attr.config = PERF_COUNT_HW_INSTRUCTIONS;
  	fds[2] = syscall (SYS_perf_event_open, &attr, 0, -1, fds[0], 0);
  	assert (fds[2] >= 0);

  	attr.type = PERF_TYPE_HARDWARE;
  	attr.config = PERF_COUNT_HW_BRANCH_MISSES;

  	attr.config = PERF_COUNT_HW_CACHE_REFERENCES;
  	fds[4] = syscall (SYS_perf_event_open, &attr, 0, -1, fds[0], 0);

b9f5c38e4a arm_mpam: Use non-atomic bitops when modifying feature bitmap
In the test__props_mismatch() kunit test we rely on the struct mpam_props
being packed to ensure memcmp doesn't consider packing. Making it packed
reduces the alignment of the features bitmap and so breaks a requirement
for the use of atomics. As we don't rely on the set/clear of these bits
being atomic, just make them non-atomic.

dd83dc1249 xhci: sideband: don't dereference freed ring when removing sideband endpoint
xhci_sideband_remove_endpoint() incorrecly assumes that the endpoint is
running and has a valid transfer ring.

Lianqin reported a crash during suspend/wake-up stress testing, and
found the cause to be dereferencing a non-existing transfer ring
'ep->ring' during xhci_sideband_remove_endpoint().

The endpoint and its ring may be in unknown state if this function
is called after xHCI was reinitialized in resume (lost power), or if
device is being re-enumerated, disconnected or endpoint already dropped.

Fix this by both removing unnecessary ring access, and by checking
ep->ring exists before dereferencing it. Also make sure endpoint is
running before attempting to stop it.

Remove the xhci_initialize_ring_info() call during sideband endpoint
removal as is it only initializes ring structure enqueue, dequeue and
cycle state values to their starting values without changing actual
hardware enqueue, dequeue and cycle state. Leaving them out of sync
is worse than leaving it as it is. The endpoint will get freed in after
this in most usecases.

If the (audio) class driver want's to reuse the endpoint after offload
then it is up to the class driver to ensure endpoint is properly set up.

USB serial fix for 6.19-rc6

Here's a fix for an f81232 enumeration issue that could prevent some
ports from being enabled (e.g. during driver rebind).

Included are also some new device ids.

All have been in linux-next with no reported issues.
