Summary
crypto: hisilicon/qm - request reserved interrupt for virtual function
Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: hisilicon/qm - request reserved interrupt for virtual function

The device interrupt vector 3 is an error interrupt for physical function and a reserved interrupt for virtual function. However, the driver has not registered the reserved interrupt for virtual function. When allocating interrupts, the number of interrupts is allocated based on powers of two, which includes this interrupt. When the system enables GICv4 and the virtual function passthrough to the virtual machine, releasing the interrupt in the driver triggers a warning.

The WARNING report is: WARNING: CPU: 62 PID: 14889 at arch/arm64/kvm/vgic/vgic-its.c:852 itsfreeite+0x94/0xb4

Therefore, register a reserved interrupt for VF and set the IRQFNOAUTOEN flag to avoid that warning.
