I'm all for opportunistically cleaning these up, but IMO it's not worth churning
code just to fix use of bare unsigned.  And if we are going to fix them, fix them
_all_, and fix the prototypes, e.g. from just a few relevant declarations:

int kvm_irq_map_chip_pin(struct kvm *kvm, unsigned irqchip, unsigned pin);  <=====

int kvm_set_irq(struct kvm *kvm, int irq_source_id, u32 irq, int level,
		bool line_status);
int kvm_set_msi(struct kvm_kernel_irq_routing_entry *irq_entry, struct kvm *kvm,
		int irq_source_id, int level, bool line_status);
int kvm_arch_set_irq_inatomic(struct kvm_kernel_irq_routing_entry *e,
			       struct kvm *kvm, int irq_source_id,
			       int level, bool line_status);
bool kvm_irq_has_notifier(struct kvm *kvm, unsigned irqchip, unsigned pin);  <=====

void kvm_notify_acked_gsi(struct kvm *kvm, int gsi);
void kvm_notify_acked_irq(struct kvm *kvm, unsigned irqchip, unsigned pin);  <=====
