...pler; for that, a GSI is allocated for each configured SINT, and irq_routing api is extended to support GSI-SINT mapping. Besides, a new vcpu exit is introduced to notify the userspace of the changes in SynIC configuraion triggered by guest writing to the corresponding MSRs.

...ults, so I can implement it as one of spelling correction algorithms as a bonus. As you know, I'm familiar enough with Xapian code base and have good skills so you could offer me any other project if you think it has higher priority. I suggest we discuss it on the IRC channel. Cheers, Nikita Smetanin.
