[PATCH 0/12] Get Xen PV shim running in qemu |

I hadn't got round to getting the PV shim running yet; I thought it would
need work on the multiboot loader. Turns out it doesn't. I *did* need to
fix a couple of brown-paper-bag bugs in the per-vCPU upcall vector support,
and implement Xen console support though. Now I can test PV guests:
$ qemu-system-x86_64 --accel kvm,xen-version=0x40011,kernel-irqchip=split \
-chardev stdio,mux=on,id=char0 -device xen-console,chardev=char0 \
-drive file=${GUEST_IMAGE},if=xen -display none -m 1G \
-kernel ~/git/xen/xen/xen -initrd ~/git/linux/arch/x86/boot/bzImage \
-append "loglvl=all -- console=hvc0 root=/dev/xvda1"
