Subject: [PATCH v3 00/28] KVM: nSVM: event fixes and migration support

This is basically the same as v2 except that it has a small fix to
"KVM: x86: enable event window in inject_pending_event", where
a second pending interrupt or NMI was not enabling the window-open
vmexit (caught by apic.flat).  In addition I've renamed
inject_pending_event to handle_processor_events.

The series now passes kvm-unit-tests and various nested hypervisor tests
so now it's *really* ready for review!  (Thanks Krish for looking at
it so far).

I'm quite pleased with the overall look of the code, though the
INT_CTL arbitration is a bit ugly.  I have plans to implement nested
vGIF and vLS, and then I will probably clean it up.
