Yes, frankly that's pretty ridiculous as it's perfectly possible to 
emulate the interrupt controller in software (and an IOMMU is not needed 
at all if you are okay with emulated or paravirtualized devices---which 
is almost always the case except for partitioning hypervisors).

Palmer, are you okay with merging RISC-V KVM?  Or should we place it in 

Either way, the best way to do it would be like this:

1) you apply patch 1 in a topic branch

2) you merge the topic branch in the risc-v tree

3) Anup merges the topic branch too and sends me a pull request.
