Commit 2fae6bb7be32 ("xen/privcmd: Add new syscall to get gsi from dev")
adds a weak reverse dependency to the config XEN_PRIVCMD definition, that
dependency causes xen-privcmd can't be loaded on domU, because dependent
xen-pciback isn't always be loaded successfully on domU.
To solve above problem, remove that dependency, and do not call
pcistub_get_gsi_from_sbdf() directly, instead add a hook in
drivers/xen/apci.c, xen-pciback register the real call function, then in
privcmd_ioctl_pcidev_get_gsi call that hook.

Only build client code if DRM_CLIENT has been selected. Automatially
do so if one of the default clients has been enabled. If client support
has been disabled, the helpers for client-related events are empty and
the regular client functions are not present.
Amdgpu has an internal DRM client, so it has to select DRM_CLIENT by
itself unconditionally.

Suspend and resume is still tied to fbdev emulation. Modeset helpers
and several drivers call drm_fb_helper_set_suspend_unlocked() to inform
the fbdev client about suspend/resume events.
To make it work with arbitrary clients, add per-client callback
functions for suspend and resume. Implement them for fbdev emulation
with the existing drm_fb_helper_set_suspend_unlocked(). Then update
DRM's modeset helpers to call the new interface.
Clients that are not fbdev can now implement suspend/resume to their
requirements.
The callback parameter holds_console_lock is a workaround for i915,
radeon and xe, which possibly call the interface while having the
console lock acquired. Even though the commit doesn't modify these
drivers, it already adds the flag to avoid churn later on. New code
should not hold the console lock.

A number of DRM-client functions serve as entry points from device
operations to client code. Moving them info a separate file will later
allow for a more fine-grained kernel configuration. For most of the
users it is sufficient to include <drm/drm_client_event.h> instead of
the full driver-side interface in <drm/drm_client.h>
v2:
- rename new files to drm_client_event.{c,h}

lockdep_set_subclass()
Syzbot reports a problem that a warning will be triggered while
searching a lock class in look_up_lock_class().
The cause of the issue is that a new name is created and used by
lockdep_set_subclass() instead of using the existing one. This results
in a lock instance has a different name pointer than previous registered
one stored in lock class, and WARN_ONCE() is triggered because of that
in look_up_lock_class().
To fix this, change lockdep_set_subclass() to use the existing name
instead of a new one. Hence, no new name will be created by
lockdep_set_subclass(). Hence, the warning is avoided.

Add a function to check that an offline CPU has left the tracing
infrastructure in a sane state.
Commit 9bb69ba4c177 ("ACPI: processor_idle: use raw_safe_halt() in
acpi_idle_play_dead()") fixed an issue where the acpi_idle_play_dead()
function called safe_halt() instead of raw_safe_halt(), which had the
side-effect of setting the hardirqs_enabled flag for the offline CPU.
On x86 this triggered warnings from lockdep_assert_irqs_disabled() when
the CPU was brought back online again later. These warnings were too
early for the exception to be handled correctly, leading to a
triple-fault.
Add lockdep_cleanup_dead_cpu() to check for this kind of failure mode,
print the events leading up to it, and correct it so that the CPU can
come online again correctly. Re-introducing the original bug now merely
results in this warning instead:
[ 61.556652] smpboot: CPU 1 is now offline
[ 61.556769] CPU 1 left hardirqs enabled!

wasteful for a clock dividor of width 8 (256 entries).
Require increasing flags size from u8 to u16 because
CLK_DIVIDER_EVEN_INTEGERS is the eighth flag. u16 is used inside struct

The existing machine_quirk() returns a pointer to a soc_acpi_mach
structure.
For SoundWire/SDCA support, we need a slightly different
functionality where a quirk function either validates or NACKs an
initial selection, based on additional firmware/DMI information.

Add new module for SDCA (SoundWire Device Class for Audio) support.
For now just add a parser to identify the SDCA revision and the
function mask.
Note that the SDCA definitions and related MIPI DisCo properties are
defined only for ACPI platforms and extracted with _DSD helpers. There
is currently no support for Device Tree in the specification, the
'depends on ACPI' reflects this design limitation. This might change
in a future revision of the specification but for SDCA 1.0 ACPI is the
only supported type of platform firmware.
The SDCA library is defined with static inline fallbacks, which will
allow for unconditional addition of SDCA support in common parts of
the code.
The design follows a four-step process:
1) Basic information related to Functions is extracted from MIPI DisCo
tables and stored in the 'struct sdw_slave'. Devm_ based memory
allocation is not allowed at this point prior to a driver probe, so we only
store the function node, address and type.
2) When a codec driver probes, it will register subdevices for each
Function identified in phase 1)
3) a driver will probe for each subdevice and addition parsing/memory
allocation takes place at this level. devm_ based allocation is highly
encouraged to make error handling manageable.
4) Before the peripheral device becomes physically attached, register
access is not permitted and the regmaps are cache-only. When
peripheral device is enumerated, the bus level uses the
'update_status' notification; after optional device-level
initialization, the codec driver will notify each of the subdevices so
that they can start interacting with the hardware.
Note that the context extracted in 1) should be arguably be handled
completely in the codec driver probe. That would however make it
difficult to use the ACPI information for machine quirks, and
e.g. select different machine driver and topologies as done for the
RT712_VB handling later in the series. To make the implementation of
quirks simpler, this patchset extracts a minimal amount of context
(interface revision and number/type of Functions) before the codec
driver probe, and stores this context in the scope of the 'struct
sdw_slave'.
The SDCA library can also be used in a vendor-specific driver without
creating subdevices, e.g. to retrieve the 'initialization-table'
values to write platform-specific values as needed.
For more technical details, the SDCA specification is available for
public downloads at https://www.mipi.org/mipi-sdca-v1-0-download

This structure is used to copy information from the 'sdw_slave'
structures, it's better to create a flexible array of 'sdw_slave'
pointers and directly access the information. This will also help
access additional information stored in the 'sdw_slave' structure,
such as an SDCA context.
This patch does not add new functionality, it only modified how the
information is retrieved.

Having removed one re-lock cycle on the entity->lock in a patch titled
"drm/sched: Optimise drm_sched_entity_push_job", with only a tiny bit
larger refactoring we can do the same optimisation on the rq->lock.
(Currently both drm_sched_rq_add_entity() and
drm_sched_rq_update_fifo_locked() take and release the same lock.)
To achieve this we make drm_sched_rq_update_fifo_locked() and
drm_sched_rq_add_entity() expect the rq->lock to be held.
We also align drm_sched_rq_update_fifo_locked(),
drm_sched_rq_add_entity() and
drm_sched_rq_remove_fifo_locked() function signatures, by adding rq as a
parameter to the latter.

When writing to a drm_sched_entity's run-queue, writers are protected
through the lock drm_sched_entity.rq_lock. This naming, however,
frequently collides with the separate internal lock of struct
drm_sched_rq, resulting in uses like this:
spin_lock(&entity->rq_lock);
spin_lock(&entity->rq->lock);
Rename drm_sched_entity.rq_lock to improve readability. While at it,

In FIFO mode (which is the default), both drm_sched_entity_push_job() and
drm_sched_rq_update_fifo(), where the latter calls the former, are
currently taking and releasing the same entity->rq_lock.

Patch series "mm: don't install PMD mappings when THPs are disabled by the
hw/process/vma".
During testing, it was found that we can get PMD mappings in processes
where THP (and more precisely, PMD mappings) are supposed to be disabled.
While it works as expected for anon+shmem, the pagecache is the
problematic bit.
For s390 KVM this currently means that a VM backed by a file located on
filesystem with large folio support can crash when KVM tries accessing the
problematic page, because the readahead logic might decide to use a
PMD-sized THP and faulting it into the page tables will install a PMD
mapping, something that s390 KVM cannot tolerate.
This might also be a problem with HW that does not support PMD mappings,
but I did not try reproducing it.
Fix it by respecting the ways to disable THPs when deciding whether we can
install a PMD mapping. khugepaged should already be taking care of not
collapsing if THPs are effectively disabled for the hw/process/vma.
This patch (of 2):
Add vma_thp_disabled() and thp_disabled_by_hw() helpers to be shared by
shmem_allowable_huge_orders() and __thp_vma_allowable_orders().

The "addr" and "is_shmem" arguments have different order in TP_PROTO and
TP_ARGS. This resulted in the incorrect trace result:

filename=text-hugepage, nr=512, result=failed
The value of "addr" is wrong because it was treated as bool value, the
type of is_shmem.
Fix the order in TP_PROTO to keep "addr" is before "is_shmem" since the
original patch review suggested this order to achieve best packing.
And use "lx" for "addr" instead of "ld" in TP_printk because address is
typically shown in hex.
After the fix, the trace result looks correct:

Arnd reported a build failure due to the BUILD_BUG_ON() statement in
alloc_kmem_cache_cpus(). The test
PERCPU_DYNAMIC_EARLY_SIZE < NR_KMALLOC_TYPES * KMALLOC_SHIFT_HIGH * sizeof(struct kmem_cache_cpu)
The factors that increase the right side of the equation:
- PAGE_SIZE > 4KiB increases KMALLOC_SHIFT_HIGH
- For the local_lock_t in kmem_cache_cpu:
- PREEMPT_RT adds an actual lock.
- LOCKDEP increases the size of the lock.
- LOCK_STAT adds additional bytes plus padding to the lockdep
structure.
The net difference with and without PREEMPT_RT is 88 bytes for the
lock_lock_t, 96 bytes for kmem_cache_cpu due to additional padding. This
is enough to exceed the 80KiB limit with 16KiB page size - the 8KiB page
size is fine.
Increase PERCPU_DYNAMIC_SIZE_SHIFT to 13 on configs with PAGE_SIZE larger
than 4KiB and LOCKDEP enabled.

The active mode is determined primarily by checking the
speed of the enumerated USB device. When USB Power Delivery
is supported, the active USB mode should be always the mode
that was used with the Enter_USB Message, regardless of the
result of the USB enumeration. The port drivers can
separately assign the mode with a dedicated API.
If USB Power Delivery Identity is supplied for the partner

Since commit ("power: supply: Drop use_cnt check from power_supply_property_is_writeable()"),
this function does not check use_cnt anymore, making it unsuitable for
general usage. As it is only used by the psy core anyways, remove it
from the public header and unexport it to avoid misusage.

Unexport nr_irqs and declare it static now that all code that reads or
modifies nr_irqs has been converted to number_of_interrupts() /
set_number_of_interrupts(). Change the type of 'nr_irqs' from 'int' into
'unsigned int' to match the return type and argument type of the
irq_get_nr_iqs() / irq_set_nr_irqs() functions.

Use the irq_get_nr_irqs() function instead of the global variable
'nr_irqs'. Cache the result of this function in a local variable in
order not to rely on CSE (common subexpression elimination). Prepare
for changing 'nr_irqs' from an exported global variable into a variable
with file scope.

Prepare for changing 'nr_irqs' from an exported global variable into a
variable with file scope.
This will prevent accidental changes of assignments to a local variable
'nr_irqs' into assignments to the global 'nr_irqs' variable.
Suppose that a patch would be submitted for review that removes a
declaration of a local variable with the name 'nr_irqs' and that that patch
does not remove all assignments to that local variable. Such a patch
converts an assignment to a local variable into an assignment into a global
variable. If the 'nr_irqs' assignment is more than three lines away from
other changes, the assignment won't be included in the diff context lines
and hence won't be visible without inspecting the modified file.
With these abstraction series applied, such accidental conversions from
assignments to a local variable into an assignment to a global variable are
converted into a compilation error.
