Christian Borntraeger e976a2b997 s390: KVM guest: virtio device support, and kvm hypercalls ... This patch implements kvm guest kernel support for paravirtualized devices and contains two parts: o a basic virtio stub using virtio_ring and external interrupts and hypercalls o full hypercall implementation in kvm_para.h Currently we dont have PCI on s390. Making virtio_pci usable for s390 seems more complicated that providing an own stub. This virtio stub is similar to the lguest one, the memory for the descriptors and the device detection is made via additional mapped memory on top of the guest storage. We use an external interrupt with extint code 0x2603 for host->guest notification. The hypercall definition uses the diag instruction for issuing a hypercall. The parameters are written in R2-R7, the hypercall number is written in R1. This is similar to the system call ABI (svc) which can use R1 for the number and R2-R6 for the parameters.
