This patch set allows user space to receive vtimer events as well as mask
them, so that we can handle all vtimer related interrupt injection from user
space, enabling us to use architected timer with user space gic emulation.

I have already voiced my concerns in the past, including face to face,
and I'm going to repeat it: I not keen at all on adding a new userspace
interface that is going to bitrot extremely quickly.

You don't have automated tests set up?  It's not going to bitrot if you
test it, either with kvm-unit-tests or just by smoke-testing Linux.
It's _for_ the raspi, but it's not limited to it.
