Right now I don't much care about 5% performance improvement in vmx, 
since noone is using it as the hardware isn't available. I'm therefore 
happy to wait for a more desirable patch than accept this a stopgap 
measure.
If you provide a patch that cleanly moves PIC (and IO-APIC, when it's 
ready) code into Xen, I will accept it in a heartbeat. I reckon that 
ought to clean up the interrupt-related parts of the PIT code too (and 
the local APIC code, when it's ready).
I really want to see vmx cleanups, bug fixes, and patches that move us 
closer to the ideal architecture that we have in mind.
