Hi, This series is mostly about adding the client/server code from David Marchand, code cleanups, and little improvements for ivshmem. Finally there is some ivshmem tests (they work fine without kvm).
The first series didn't get much feedback. As suggested by Andrew Jones, this second version adds support for hugepage shm, in qemu with a hostmem backend and a fix in the server side (instead of relying on bad/old glibc hack). It also adds irqfd usage for msix notification.
