Aren't you using upstream qemu?

Store irq routing table pointer in the irqfd object,
and use that to inject MSI directly without bouncing out to
a kernel thread.
While we touch this structure, rearrange irqfd fields to make fastpath
better packed for better cache utilization.

No, I believe your patch is correct and the lock should be there. Did you test
with spinlock debugging just to be sure?
Sorry but no.
I have no experience with cpu hotplug.
So I thought it would take too much time to do real test by myself and repo
Clear the vapic address immediately after reset. This allows dual-boot guests
to work efficiently, and more importantly, works around the bios using
'rep insb' to read in the option rom and confusing the vapic machinery.
