Merge tag 'irq-core-2026-04-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core irq updates from Thomas Gleixner:
- Invoke add_interrupt_randomness() in handle_percpu_devid_irq() and
cleanup the workaround in the Hyper-V driver, which would now invoke
it twice on ARM64. Removing it from the driver requires to add it to
the x86 system vector entry point
- Remove the pointles cpu_read_lock() around reading CPU possible mask,
which is read only after init
- Add documentation for the interaction between device tree bindings
and the interrupt type defines in irq.h
- Delete stale defines in the matrix allocator and the equivalent in
loongarch
* tag 'irq-core-2026-04-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
Drivers: hv: Move add_interrupt_randomness() to hypervisor callback sysvec
genirq/chip: Invoke add_interrupt_randomness() in handle_percpu_devid_irq()
genirq/affinity: Remove cpus_read_lock() while reading cpu_possible_mask
genirq/matrix, LoongArch: Delete IRQ_MATRIX_BITS leftovers
genirq: Document interaction between <linux/irq.h> and DT binding defines
