It's fundamentally the same, but more robust to occasional long delays

In particular, the old code was susceptible to failing if the initial

The code is mostly generic, so the x86 in the subject is a little misleading.
What keeps the Kconfig symbol in x86 anyway? Is there a reason why

VT-d Posted-Interrupts is an enhancement to CPU side Posted-Interrupt.
With VT-d Posted-Interrupts enabled, external interrupts from
direct-assigned devices can be delivered to guests without VMM
intervention when guest is running in non-root mode.
You can find the VT-d Posted-Interrtups Spec. in
cc'ing Hans and quoting whole message.
Hans, can you please review this one?
Thanks.

Hello, Aleksa.
Looks pretty good to me in general. Some minor comments below.
