Merge tag 'irq_urgent_for_v6.8_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq fixes from Borislav Petkov:

- Make sure GICv4 always gets initialized to prevent a kexec-ed kernel
from silently failing to set it up

- Do not call bus_get_dev_root() for the mbigen irqchip as it always
returns NULL - use NULL directly

- Fix hardware interrupt number truncation when assigning MSI
interrupts

- Correct sending end-of-interrupt messages to disabled interrupts
lines on RISC-V PLIC

irqchip/gic-v3-its: Do not assume vPE tables are preallocated
irqchip/mbigen: Don't use bus_get_dev_root() to find the parent
PCI/MSI: Prevent MSI hardware interrupt number truncation
irqchip/sifive-plic: Enable interrupt if needed before EOI
