vulnerability has been resolved:\n\nirqchip/gic-v4: Don't advertise VLPIs if no ITS is probed\n\nWhen accidentally setting “kvm-arm.vgic_v4_enable=1” on a system that has\nno MSI controller device tree node and GICv4, it results a panic as\n“gic_domain” is NULL and the kernel attempts to access it.\n\n    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000028\n
