### Description

In the Linux kernel, the following vulnerability has been resolved:irqchip/gic-v3-its: Don't enable interrupts in its_irq_set_vcpu_affinity()The following call-chain leads to enabling interrupts in a nested interruptdisabled section:irq_set_vcpu_affinity()  irq_get_desc_lock()     raw_spin_lock_irqsave()   <--- Disable interrupts  its_irq_set_vcpu_affinity()     guard(raw_spinlock_irq)   <--- Enables interrupts when leaving the guard()  irq_put_desc_unlock()        <--- Warns because interrupts are enabledThis was broken in commit b97e8a2f7130, which replaced the originalraw_spin_[un]lock() pair with guard(raw_spinlock_irq).Fix the issue by using guard(raw_spinlock).[ tglx: Massaged change log ]
