On the surface it seems reasonable.
Thomas Gleixner has been working on greatly revamping a bunch of the x86
interrupt code, and this might interact with his stuff, so it would be
good if he could comment on it.
[tglx: what they're apparently working on is to redirect APIC interrupts
to Xen event channels so they don't have to interact with the simulated
memory-mapped APIC. It's "paravirtualization light".]
