[ Upstream commit 7a223e06b1a411cef6c4cd7a9b9a33c8d225b10e ] In __apic_accept_irq() interface trig_mode is int and actually on some code paths it is set above u8: kvm_apic_set_irq() extracts it from 'struct kvm_lapic_irq' where trig_mode is u16. This is done on purpose as e.g. kvm_set_msi_irq() sets it to (1 << 15) & e->msi.data kvm_apic_local_deliver sets it to reg & (1 << 15). Fix the immediate issue by making 'tm' into u16. We may also want to adjust __apic_accept_irq() interface and use proper sizes for vector, level, trig_mode but this is not urgent.
