Pull irq driver updates from Thomas Gleixner:
- Support for hard indices on RISC-V. The hart index identifies a hart (core) within a specific interrupt domain in RISC-V's Priviledged Architecture.
- Rework of the RISC-V MSI driver
This moves the driver over to the generic MSI library and solves the affinity problem of unmaskable PCI/MSI controllers. Unmaskable PCI/MSI controllers are prone to lose interrupts when the MSI message is updated to change the affinity because the message write consists of three 32-bit subsequent writes, which update address and data. As these writes are non-atomic versus the device raising an interrupt, the device can observe a half written update and issue an interrupt on the wrong vector. This is mitiated by a carefully orchestrated step by step update and the observation of an eventually pending interrupt on the CPU which issues the update. The algorithm follows the well established method of the X86 MSI driver.
- A new driver for the RISC-V Sophgo SG2042 MSI controller
- Overhaul of the Renesas RZQ2L driver
Simplification of the probe function by using devm_*() mechanisms, which avoid the endless list of error prone gotos in the failure paths.
- Expand the Renesas RZV2H driver to support RZ/G3E SoCs
- A workaround for Rockchip 3568002 erratum in the GIC-V3 driver to ensure that the addressing is limited to the lower 32-bit of the physical address space.
- Add support for the Allwinner AS23 NMI controller
- Expand the IMX irqsteer driver to handle up to 960 input interrupts
- The usual small updates, cleanups and device tree changes

Document optional property "riscv,hart-indexes"
The RISC-V APLIC specification defines "hart index" in:

dt-bindings: interrupt-controller: Add risc-v,aplic hart indexes
Document optional property "riscv,hart-indexes"
The RISC-V APLIC specification defines "hart index" in:
https://github.com/riscv/riscv-aia
Within a given interrupt domain, each of the domain’s harts has a unique index number in the range 0 to 2^14 − 1 (= 16,383). The index number a domain associates with a hart may or may not have any relationship to the unique hart identifier (“hart ID”) that the RISC-V Privileged Architecture assigns to the hart. Two different interrupt domains may employ entirely different index numbers for the same set of harts.
Further, this document says in "4.5 Memory-mapped control region for an interrupt domain":
The array of IDC structures may include some for potential hart index numbers that are not actual hart index numbers in the domain. For example, the first IDC structure is always for hart index 0, but 0 is not necessarily a valid index number for any hart in the domain.
Support arbitrary hart indexes specified in a optional APLIC property "riscv,hart-indexes" which is specificed as an array of u32 elements, one per interrupt target. If this property is not specified, fallback to use the logical hart indices within the domain.

Merge tag 'irq-core-2024-05-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull interrupt subsystem updates from Thomas Gleixner: "Core code:
- Interrupt storm detection for the lockup watchdog:
Lockups which are caused by interrupt storms are not easy to debug because there is no information about the events which make the lockup detector trigger.
To make this more user friendly, provide an extenstion to interrupt statistics which allows to take snapshots and an interface to retrieve the delta to the snapshot. Use this new mechanism in the watchdog code to do a two stage lockup analysis by taking the snapshot and printing the deltas for the topmost active interrupts on the second trigger.
Note: This contains both the interrupt and the watchdog changes as the latter depend on the former obviously.
- Avoid summation loops in the /proc/interrupts output and use the global counter when possible
- Skip suspended interrupts on CPU hotplug operations to ensure that they are not delivered before the system resumes the device drivers when coming out of suspend.
- On CPU hot-unplug interrupts which are affine to the outgoing CPU are migrated to a different CPU in the affinity mask. This can fail when the CPUs have no vectors left. Instead of giving up try to migrate it to any online CPU and thereby breaking the affinity setting in order to prevent a stale device interrupt which targets an offline CPU
- The usual small cleanups
Driver code:
- Support for the RISCV AIA MSI controller
- Make the interrupt allocation for the Loongson PCH controller more flexible to prevent vector exhaustion
- The usual set of cleanups and fixes all over the place"
