[Qemu-commits] [COMMIT 6f725c1] provide tests for pit in kernel and irqchip in kernel

[Anthony Liguori]

From: Glauber Costa <address@hidden>

KVM can have an in-kernel pit or irqchip. While we don't implement it
yet, having a way for test for it (that always returns zero) will allow us
to reuse code in qemu-kvm that tests for it.
