----------------------------------------------------------------
Two new features are added by this patch set:
- The floating interrupt controller (flic) that allows us to inject,
clear and inspect non-vcpu local interrupts. This also gives us an
opportunity to fix deficiencies in our existing interrupt definitions.
- Support for asynchronous page faults via the pfault mechanism. Testing
show significant guest performance improvements under host swap.
----------------------------------------------------------------
