KVM: PPC: Convert DAR to shared page.
The DAR register contains the address a data page fault occured at. This register behaves pretty much like a simple data storage register that gets written to on data faults. There is no hypervisor interaction required on read or write. This patch converts all users of the current field to the shared page.
