[Xen-devel] [PATCH 2/3] piix4acpi, xen: Clarify that the qemu_set_irq calls just do an IRQ pulse.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

The "qemu_cpu_notify" raises and lowers the ACPI SCI line when the
vCPU state has changed.

Instead of doing the two functions, just use one function that
describes exactly what it does.
