That is needed in case interrupt injection failed because the process of injecting the interrupt (usually pushing data on the stack) writes to a write-protected page table.
I guess we need nmi_pending here as well. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
