Subject: KVM: VMX: include all IRQ window exits in statistics
X-Git-Tag: firefly_0821_release~16439^2~138

KVM: VMX: include all IRQ window exits in statistics

irq_window_exits only tracks IRQ window exits due to user space
requests, nmi_window_exits include all exits. The latter makes more
sense, so let's adjust irq_window_exits accounting.
