Subject: [PATCH] kvm: Split arch/x86/kvm/irq.c to two parts.
Moving irq ack notification logic as common, and make
it shared with ia64 side.
+/* This should be called with the kvm->lock mutex held */
+void kvm_set_irq(struct kvm *kvm, int irq, int level)
+{
+ /* Not possible to detect if the guest uses the PIC or the
+ * IOAPIC. So set the bit in both. The guest will ignore
+ * writes to the unused one.
+ */
+ kvm_ioapic_set_irq(kvm->arch.vioapic, irq, level);
+#ifdef X86
+ kvm_pic_set_irq(pic_irqchip(kvm), irq, level);
+#endif
+}
+
This needs to be CONFIG_X86, not X86. As is, Windows doesn't even
boot. Fixing it causes compile errors for missing declarations and
pic_irqchip().
Please fix ASAP and test much more carefully. Meanwhile I am reverting
the patchset.

I have a truly marvellous patch that fixes the bug which this
