38b20968f3 drm/amdgpu: move scheduler wqueue handling into callbacks
Move the scheduler wqueue stopping and starting into
the ring reset callbacks.  On some IPs we have to reset
an engine which may have multiple queues.  Move the wqueue
handling into the backend so we can handle them as needed
based on the type of reset available.

43ca5eb94b drm/amdgpu: move guilty handling into ring resets
Move guilty logic into the ring reset callbacks.  This
allows each ring reset callback to better handle fence
errors and force completions in line with the reset
behavior for each IP.  It also allows us to remove
the ring guilty callback since that logic now lives
in the reset callback.

a29e067bd3 drm/amdkfd: Don't call mmput from MMU notifier callback
If the process is exiting, the mmput inside mmu notifier callback from
compactd or fork or numa balancing could release the last reference
of mm struct to call exit_mmap and free_pgtable, this triggers deadlock
with below backtrace.

The deadlock will leak kfd process as mmu notifier release is not called
and cause VRAM leaking.

The fix is to take mm reference mmget_non_zero when adding prange to the
deferred list to pair with mmput in deferred list work.

If prange split and add into pchild list, the pchild work_item.mm is not
used, so remove the mm parameter from svm_range_unmap_split and
svm_range_add_child.

The backtrace of hung task:

0043ec26d8 drm/amdgpu/gfx9: Add Cleaner Shader Support for GFX9.x GPUs
Enable the cleaner shader for other GFX9.x series of GPUs to provide
data isolation between GPU workloads. The cleaner shader is responsible
for clearing the Local Data Store (LDS), Vector General Purpose
Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which
helps prevent data leakage and ensures accurate computation results.

This update extends cleaner shader support to GFX9.x GPUs, previously
available for GFX9.4.2. It enhances security by clearing GPU memory
between processes and maintains a consistent GPU state across KGD and
KFD workloads.

9bed716f87 drm/amd/pm: Add support to set min ISP clocks
Add support to set ISP clocks for SMU v14.0.0. ISP driver
uses amdgpu_dpm_set_soft_freq_range() API to set clocks via
SMU interface than communicating with PMFW directly.

amdgpu_dpm_set_soft_freq_range() is updated to take in any
pp_clock_type than limiting to support only PP_SCLK to allow
ISP and other driver modules to set the min/max clocks. Any
clock specific restrictions are expected to be taken care in
SOC specific SMU implementations instead of generic amdgpu_dpm
and amdgpu_smu interfaces.

5fb90421fa drm/amdgpu: fix slab-use-after-free in amdgpu_userq_mgr_fini+0x70c
The issue was reproduced on NV10 using IGT pci_unplug test.
It is expected that `amdgpu_driver_postclose_kms()` is called prior to `amdgpu_drm_release()`.
However, the bug is that `amdgpu_fpriv` was freed in `amdgpu_driver_postclose_kms()`, and then
later accessed in `amdgpu_drm_release()` via a call to `amdgpu_userq_mgr_fini()`.
As a result, KASAN detected a use-after-free condition, as shown in the log below.
The proposed fix is to move the calls to `amdgpu_eviction_fence_destroy()` and
`amdgpu_userq_mgr_fini()` into `amdgpu_driver_postclose_kms()`, so they are invoked before
`amdgpu_fpriv` is freed.

This also ensures symmetry with the initialization path in `amdgpu_driver_open_kms()`,
where the following components are initialized:
- `amdgpu_userq_mgr_init()`
- `amdgpu_eviction_fence_init()`
- `amdgpu_ctx_mgr_init()`

Correspondingly, in `amdgpu_driver_postclose_kms()` we should clean up using:
- `amdgpu_userq_mgr_fini()`
- `amdgpu_eviction_fence_destroy()`
- `amdgpu_ctx_mgr_fini()`

This change eliminates the use-after-free and improves consistency in resource management between open and close paths.

commit 017fbb6690 ("drm/amdgpu/discovery: check ip_discovery fw file

for some specific products. If it's not found then it will fallback to
hardcoded values. However if it's not found there is also a lot of noise
about missing files and errors.

Adjust the error handling to decrease most messages to DEBUG and to show
users less about missing files.

90adb32480 drm/amd/display: Include EQU Prefetch Bandwidth For Bandwidth Calculations
[Why]
Pixel data bandwidth required in mode programming (MP) ends up being
higher than what was calculated in mode support (MS) even though
the prefetch bandwidths calculated in MP are lower than the MS ones.

MP used a different equ prefetch schedule than MS which lead a
slight difference in parameters. This resulted in the pixel data
bandwidth in MP to be higher than MS.

[How]
Rename the RequiredPrefetchBWOTO term so it can be applied generically.
Update the value with the EQU bandwidth if the EQU schedule is used.
Get the max prefetch bandwidth that MS calculated and use it
as part of the calculations for required bandwidth.

helps prevent data leakage and ensures accurate computation results.

This update extends cleaner shader support to GFX9.x GPUs, previously
available for GFX9.4.2. It enhances security by clearing GPU memory
between processes and maintains a consistent GPU state across KGD and
KFD workloads.

0d57dd1765 drm/amd/display: Add more checks for DSC / HUBP ONO guarantees
[WHY]
For non-zero DSC instances it's possible that the HUBP domain required
to drive it for sequential ONO ASICs isn't met, potentially causing
the logic to the tile to enter an undefined state leading to a system

Add more checks to ensure that the HUBP domain matching the DSC instance

d358a51444 drm/amd/display: Get LTTPR IEEE OUI/Device ID From Closest LTTPR To Host
[WHY]
These fields are read for the explicit purpose of detecting embedded LTTPRs
(i.e. between host ASIC and the user-facing port), and thus need to
calculate the correct DPCD address offset based on LTTPR count to target
the appropriate LTTPR's DPCD register space with these queries.

[HOW]
Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried
via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a
laptop) will always be addressible using the max LTTPR count seen by the
host. Therefore we simply need to use a recently added helper function to
calculate the correct DPCD address to target potentially embedded LTTPRs
based on the received LTTPR count.

[Why]
Common modes are added to eDP for compatibility in clone mode, but
not all panels support them.  Non-native modes were disabled in the past
but this caused problems because compositors didn't use scaling for non
native modes. Now non-native modes on eDP will enable the scaler by
default.

Check the connector type.  If the connector is eDP avoid adding common
modes.

In DML2, the current method to determine a

voltage levels sequentially from the lowest,
until one is found that can support the
mode. It causes cursor lag due to low
performance.

[How]
We apply two methods for mode validation.
1) DC_VALIDATE_MODE_ONLY: only the
maximum voltage level is checked to
determine whether the mode is supported, which
improves performance and eliminate cursor lag.

2) DC_VALIDATE_MODE_AND_STATE_INDEX: when
the optimal voltage level is required, check
the voltage level from the lowest until
a suitable one is found found and returns
its index.

3bab282dfe drm/amdgpu: Use logical instance ID for SDMA v4_4_2 queue operations
Simplify SDMA v4_4_2 queue reset and stop operations by:
1. Removing GET_INST(SDMA0) conversion for ring->me
2. Using the logical instance ID (ring->me) directly
3. Maintaining consistent behavior with other SDMA queue operations

This change aligns with the existing queue handling logic where
ring->me already represents the correct instance identifier.

5efa6217c2 drm/amdgpu: Fix SDMA engine reset with logical instance ID
This commit makes the following improvements to SDMA engine reset handling:

1. Clarifies in the function documentation that instance_id refers to a logical ID
2. Adds conversion from logical to physical instance ID before performing reset
   using GET_INST(SDMA0, instance_id) macro
3. Improves error messaging to indicate when a logical instance reset fails
4. Adds better code organization with blank lines for readability

The change ensures proper SDMA engine reset by using the correct physical
instance ID while maintaining the logical ID interface for callers.

V2: Remove harvest_config check and convert directly to physical instance (Lijo)

45cc102f8e drm/amd/display: Destroy cached state in complete() callback
[Why]
When the suspend sequence has been aborted after prepare() but
before suspend() the resume() callback never gets called. The PM core
will call complete() when this happens. As the state has been cached
in prepare() it needs to be destroyed in complete() if it's still around.

[How]
Create a helper for destroying cached state and call it both in resume()
and complete() callbacks. If resume has been called the state will be
destroyed and it's a no-op for complete().  If resume hasn't been called
(such as an aborted suspend) then destroy the state in complete().

f948770387 drm/amd/display: Deprecate Loading Bounding Box From DMUB On DCN4
[WHY]
dml2_soc_bb struct can continuously receive updates for future ASICs.
Alignment issues may arise since VBIOS DMCUB contains an older version of
the SOC BB.

Populating the bounding box with values from DMCUB is no longer necessary
since values such as UCLK will be overridden by values acquired by PMFW
anyways.

[HOW]
Use bb_from_dmub to store DCN specific bounding box parameters in DMCUB.
Add helpers to translate DCN specific struct to the corresponding
dml2_soc_bb field.

To avoid alignment issues:
Deprecate applying DMCUB SoC BB for DCN4

For future projects:
Create a flattened struct containing all sensitive parameters in the
bounding box. New parameters can be added to the bottom of the new struct
as needed.

791897f5c7 drm/amd/display: Get LTTPR IEEE OUI/Device ID From Closest LTTPR To Host
[WHY]
These fields are read for the explicit purpose of detecting embedded LTTPRs
(i.e. between host ASIC and the user-facing port), and thus need to
calculate the correct DPCD address offset based on LTTPR count to target
the appropriate LTTPR's DPCD register space with these queries.

[HOW]
Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried
via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a
laptop) will always be addressible using the max LTTPR count seen by the
host. Therefore we simply need to use a recently added helper function to
calculate the correct DPCD address to target potentially embedded LTTPRs
based on the received LTTPR count.

2f405eb45c drm/amdgpu: enable pdb0 for hibernation on SRIOV
When switching to new GPU index after hibernation and then resume,
VRAM offset of each VRAM BO will be changed, and the cached gpu
addresses needed to updated.

This is to enable pdb0 and switch to use pdb0-based virtual gpu
address by default in amdgpu_bo_create_reserved(). since the virtual
addresses do not change, this can avoid the need to update all
cached gpu addresses all over the codebase.

add amdgpu_bo_fb_aper_addr() and update the cached GPU addresses to use
the FB aperture address for SMU and PSP.

2 reasons for this change:
1. when pdb0 is enabled, gpu addr from amdgpu_bo_create_kernel() is GART
aperture address, it is not compatible with SMU and PSP, it need to be
updated to use FB aperture address.
2. Since FB aperture address will change after switching to new GPU

183bccafa1 drm: Create a task info option for wedge events
When a device get wedged, it might be caused by a guilty application.
For userspace, knowing which task was involved can be useful for some
situations, like for implementing a policy, logs or for giving a chance
for the compositor to let the user know what task was involved in the
problem.  This is an optional argument, when the task info is not
available, the PID and TASK string won't appear in the event string.

Sometimes just the PID isn't enough giving that the task might be already
dead by the time userspace will try to check what was this PID's name,
so to make the life easier also notify what's the task's name in the user
event.

   - Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
     Errors (Karolina Stolarek)

   - Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
     controls on interval and burst count, to avoid flooding logs and
     RCU stall warnings (Jon Pan-Doh)

  Power management:

   - Increment PM usage counter when probing reset methods so we don't
     try to read config space of a powered-off device (Alex Williamson)

   - Set all devices to D0 during enumeration to ensure ACPI opregion is
     connected via _REG (Mario Limonciello)

  Power control:

   - Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
     the filename paths. Retain old deprecated symbols for
     compatibility, except for the pwrctrl slot driver
     (PCI_PWRCTRL_SLOT) (Johan Hovold)

   - When unregistering pwrctrl, cancel outstanding rescan work before
     cleaning up data structures to avoid use-after-free issues (Brian
     Norris)

  Bandwidth control:

   - Simplify link bandwidth controller by replacing the count of Link
     Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
     flag (Ilpo Järvinen)

   - Update the Link Speed after retraining, since the Link Speed may
     have changed (Ilpo Järvinen)

  PCIe native device hotplug:

   - Ignore Presence Detect Changed caused by DPC.

     pciehp already ignores Link Down/Up events caused by DPC, but on
     slots using in-band presence detect, DPC causes a spurious Presence
     Detect Changed event (Lukas Wunner)

   - Ignore Link Down/Up caused by Secondary Bus Reset.

     On hotplug ports using in-band presence detect, the reset causes a
     Presence Detect Changed event, which mistakenly caused teardown and
     re-enumeration of the device. Drivers may need to annotate code
     that resets their device (Lukas Wunner)

  Virtualization:

   - Add an ACS quirk for Loongson Root Ports that don't advertise ACS
     but don't allow peer-to-peer transactions between Root Ports; the
     quirk allows each Root Port to be in a separate IOMMU group (Huacai
     Chen)

  Endpoint framework:

   - For fixed-size BARs, retain both the actual size and the possibly
     larger size allocated to accommodate iATU alignment requirements
     (Jerome Brunet)

   - Simplify ctrl/SPAD space allocation and avoid allocating more space
     than needed (Jerome Brunet)

   - Correct MSI-X PBA offset calculations for DesignWare and Cadence
     endpoint controllers (Niklas Cassel)

   - Align the return value (number of interrupts) encoding for
     pci_epc_get_msi()/pci_epc_ops::get_msi() and
     pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

   - Align the nr_irqs parameter encoding for
     pci_epc_set_msi()/pci_epc_ops::set_msi() and
     pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

  Common host controller library:

   - Convert pci-host-common to a library so platforms that don't need
     native host controller drivers don't need to include these helper
     functions (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Extract ECAM bridge creation helper from pci_host_common_probe() to
     separate driver-specific things like MSI from PCI things (Marc
     Zyngier)

   - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
     varying capabilities (Marc Zyngier)

   - Skip ports disabled in DT when setting up ports (Janne Grunau)

   - Add t6020 compatible string (Alyssa Rosenzweig)

   - Add T602x PCIe support (Hector Martin)

   - Directly set/clear INTx mask bits because T602x dropped the
     accessors that could do this without locking (Marc Zyngier)

   - Move port PHY registers to their own reg items to accommodate
     T602x, which moves them around; retain default offsets for existing
     DTs that lack phy%d entries with the reg offsets (Hector Martin)

   - Stop polling for core refclk, which doesn't work on T602x and the
     bootloader has already done anyway (Hector Martin)

   - Use gpiod_set_value_cansleep() when asserting PERST# in probe
     because we're allowed to sleep there (Hector Martin)

     loadable drivers when they are removed (Siddharth Vadapalli)

  Freescale i.MX6 PCIe controller driver:

   - Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
     (Richard Zhu)

   - Remove redundant dw_pcie_wait_for_link() from
     imx_pcie_start_link(); since the DWC core does this, imx6 only
     needs it when retraining for a faster link speed (Richard Zhu)

   - Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

   - Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
     some cases, the controller can't exit 'L23 Ready' through Beacon or
     PERST# deassertion (Richard Zhu)

   - Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
     controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
     GT/s, causing timeouts in L1 (Richard Zhu)

   - Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

   - Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

   - Create debugfs directory for 'aspm_state_cnt' only when
     CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
     Zhang)

  Qualcomm PCIe controller driver:

   - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
     equalization presets (Krishna Chaitanya Chundru)

   - Read Maximum Link Width from the Link Capabilities register if DT
     lacks 'num-lanes' property (Krishna Chaitanya Chundru)

   - Add Physical Layer 64 GT/s Capability ID and register offsets for
     8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
     Chundru)

   - Add generic dwc support for configuring lane equalization presets
     (Krishna Chaitanya Chundru)

   - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)

  Renesas R-Car PCIe controller driver:

   - Describe endpoint BAR 4 as being fixed size (Jerome Brunet)

   - Document how to obtain R-Car V4H (r8a779g0) controller firmware
     (Yoshihiro Shimoda)

  Rockchip PCIe controller driver:

   - Reorder rockchip_pci_core_rsts because
     reset_control_bulk_deassert() deasserts in reverse order, to fix a
     link training regression (Jensen Huang)

   - Mark RK3399 as being capable of raising INTx interrupts (Niklas
     Cassel)

  Rockchip DesignWare PCIe controller driver:

   - Check only PCIE_LINKUP, not LTSSM status, to determine whether the
     link is up (Shawn Lin)

   - Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
     for Root Complex and Endpoint modes (Shawn Lin)

   - Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
     of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
     resets non-sticky registers (Shawn Lin)

   - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
     (Diederik de Haas)

  Synopsys DesignWare PCIe controller driver:

   - Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
     more robust; this will not affect the intended link width if all
     lanes are functional (Wenbin Yao)

   - Return bool (not int) for link-up check in dw_pcie_ops.link_up()
     and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
     keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
     tegra194, uniphier, visconti (Hans Zhang)

   - Add debugfs support for exposing DWC device-specific PTM context

269c1d1443 drm/amd/display: replace fast_validate with enum dc_validate_mode
[Why]
The boolean fast_validate is used as an
input parameter in multiple functions. To
support more scenarios, we are
replacing it with enum dc_validate_mode.

[How]
The enum dc_validate_mode introduces three
possible values:
1) DC_VALIDATE_MODE_AND_PROGRAMMING:
   Apply the mode to hardware
2) DC_VALIDATE_MODE_ONLY:
   Check whether the mode can be supported
3) DC_VALIDATE_MODE_AND_STATE_INDEX:
   Check if the mode can be supported, and
   determine the optimal voltage level
   needed to support it.

[Why]
When doing 2:1 downscaling on a YUV sub-sampled format, the chroma

[How]
The indirect buffer acts as a shared buffer on the driver side,
mapped to DMUB's internal CW7 address. Its source address and

335f1e797c drm/amdgpu: Fix integer overflow in amdgpu_gem_add_input_fence()
The "num_syncobj_handles" is a u32 value that comes from the user via the
ioctl.  On 32bit systems the "sizeof(uint32_t) * num_syncobj_handles"

98a46a4089 drm/amdgpu: Fix integer overflow issues in amdgpu_userq_fence.c
This patch only affects 32bit systems.  There are several integer
overflows bugs here but only the "sizeof(u32) * num_syncobj"
multiplication is a problem at runtime.  (The last lines of this patch).

These variables are u32 variables that come from the user.  The issue
is the multiplications can overflow leading to us allocating a smaller
buffer than intended.  For the first couple integer overflows, the
syncobj_handles = memdup_user() allocation is immediately followed by
a kmalloc_array():

	syncobj = kmalloc_array(num_syncobj_handles, sizeof(*syncobj), GFP_KERNEL);

In that situation the kmalloc_array() works as a bounds check and we
haven't accessed the syncobj_handlesp[] array yet so the integer overflow
is harmless.

But the "num_syncobj" multiplication doesn't have that and the integer
overflow could lead to an out of bounds access.

General Purpose Registers (VGPRs), and Scalar General Purpose Registers

- Simplified the logic in the SGPR clearing section, ensuring all SGPRs

With the goal of reducing the need for drivers to touch (and dereference)
fence->ops, we move the 64-bit seqnos flag from struct dma_fence_ops to
the fence->flags.

Drivers which were setting this flag are changed to use new
dma_fence_init64() instead of dma_fence_init().

v2:
 * Streamlined init and added kerneldoc.

0ef2803173 drm/amdgpu/vcn1: read back register after written
V3: drop changes where readbacks have implemented. This patch set
    is to add readbacks only.

V2: use common register UVD_STATUS for readback (standard PCI MMIO
    behavior, i.e. readback post all writes to let the writes hit
    the hardware)
    add readback in ..._stop() for more coverage.

Similar to the changes made for VCN v4.0.5 where readback to post the
writes to avoid race with the doorbell, the addition of register
readback support in other VCN versions is intended to prevent potential
race conditions, even though such issues have not been observed yet.
This change ensures consistency across different VCN variants and helps
avoid similar issues. The overhead introduced is negligible.

Pull drm updates from Dave Airlie:
 "As part of building up nova-core/nova-drm pieces we've brought in some
  rust abstractions through this tree, aux bus being the main one, with
  devres changes also in the driver-core tree. Along with the drm core
  abstractions and enough nova-core/nova-drm to use them. This is still
  all stub work under construction, to build the nova driver upstream.

  The other big NVIDIA related one is nouveau adds support for
  Hopper/Blackwell GPUs, this required a new GSP firmware update to
  570.144, and a bunch of rework in order to support multiple fw
  interfaces.

  There is also the introduction of an asahi uapi header file as a
  precursor to getting the real driver in later, but to unblock
  userspace mesa packages while the driver is trapped behind rust
  enablement.

  Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
  and msm being the main ones, and some changes to vsprintf.

4f7fa5fa41 drm: Get rid of drm_sched_job.id
Its only purpose was for trace events, but jobs can already be
uniquely identified using their fence.

The downside of using the fence is that it's only available
after 'drm_sched_job_arm' was called which is true for all trace
events that used job.id so they can safely switch to using it.

2956554823 drm/sched: Store the drm client_id in drm_sched_fence
This will be used in a later commit to trace the drm client_id in
some of the gpu_scheduler trace events.

This requires changing all the users of drm_sched_job_init to
add an extra parameter.

The newly added drm_client_id field in the drm_sched_fence is a bit
of a duplicate of the owner one. One suggestion I received was to
merge those 2 fields - this can't be done right now as amdgpu uses
some special values (AMDGPU_FENCE_OWNER_*) that can't really be
translated into a client id. Christian is working on getting rid of
those; when it's done we should be able to squash owner/drm_client_id
together.

97851c6016 lib/ratelimit: Reduce false-positive and silent misses
Changes
 -------
 
 * Reduce open-coded use of ratelimit_state structure fields.
 * Convert the ->missed field to atomic_t.
 * Count misses that are due to lock contention.
 * Eliminate jiffies=0 special case.
 * Reduce ___ratelimit() false-positive rate limiting (Petr Mladek).
 * Allow zero ->burst to hard-disable rate limiting.
 * Optimize away atomic operations when a miss is guaranteed.
 * Warn if ->interval or ->burst are negative (Petr Mladek).
 * Simplify the resulting code.
 
 A smoke test and stress test have been created, but they are not yet ready
 for mainline.  With luck, we will offer them for the v6.17 merge window.

Pull rate-limit updates from Paul McKenney:
 "lib/ratelimit: Reduce false-positive and silent misses:

   - Reduce open-coded use of ratelimit_state structure fields.

   - Convert the ->missed field to atomic_t.

   - Count misses that are due to lock contention.

   - Eliminate jiffies=0 special case.

   - Reduce ___ratelimit() false-positive rate limiting (Petr Mladek).

   - Allow zero ->burst to hard-disable rate limiting.

   - Optimize away atomic operations when a miss is guaranteed.

   - Warn if ->interval or ->burst are negative (Petr Mladek).

   - Simplify the resulting code.

  A smoke test and stress test have been created, but they are not yet
  ready for mainline. With luck, we will offer them for the v6.17 merge
  window"

2bd1bea5fa A set of cleanups for the generic interrupt subsystem:
- Consolidate on one set of functions for the interrupt domain code to
     get rid of pointlessly duplicated code with only marginal different
     semantics.
 
   - Update the documentation accordingly and consolidate the coding style
     of the irqdomain header.
