Merge tag 'xenfv-2' of git://git.infradead.org/users/dwmw2/qemu into staging
Enable PV backends with Xen/KVM emulation
This is phase 2, following on from the basic platform support which was
already merged.
• Add a simple single-tenant internal XenStore implementation
• Indirect Xen gnttab/evtchn/foreignmem/xenstore through operations table
• Provide emulated back ends for Xen operations
• Header cleanups to allow PV back ends to build without Xen itself
• Enable PV back ends in emulated mode
• Documentation update
Tested-by: Paul Durrant <paul@xen.org>
... on real Xen (master branch, 4.18) with a Debian guest.
