Event injection in nSVM does not use check_nested_events, which means it
is basically broken. As a first step, this fixes interrupt injection
which is probably the most complicated case due to the interactions
with V_INTR_MASKING and the host EFLAGS.IF.
This series fixes Cathy's test case that I have sent earlier.

Paolo Bonzini (4):
KVM: nSVM: do not change host intercepts while nested VM is running
KVM: nSVM: ignore L1 interrupt window while running L2 with
V_INTR_MASKING=1
KVM: nSVM: implement check_nested_events for interrupts
KVM: nSVM: avoid loss of pending IRQ/NMI before entering L2
