Using kvm_mmu_prepare_zap_page() and kvm_mmu_commit_zap_page() to
split kvm_mmu_zap_page() function, then we can:
- traverse hlist safely
- easily to gather remote tlb flush which occurs during page zapped

This patch adds initial support for the -machine option, that allows
command line specification of machine attributes.
Besides its value per-se, it is the saner way we found to

PCI device in the guest. This patch also supports interrupts between guest by
communicating over a unix domain socket. This patch applies to the qemu-kvm

This patch adds a driver for my shared memory PCI device using the uio_pci
interface. The driver has three memory regions. The first memory region is for
device registers for sending interrupts. The second BAR is for receiving MSI-X
interrupts and the third memory region maps the shared memory.
