What exactly do you want to kill?  In-kernel local APIC obviously needs to stay
for APICv/AVIC.

And IMO, encouraging userspace I/O APIC emulation is a net negative for KVM and
the community as a whole, as the number of VMMs in use these days results in a
decent amount of duplicated work in userspace VMMs, especially when accounting
for hardware and software quirks.
