    KVM: PPC: Convert SRR0 and SRR1 to shared page · de7906c3
    Alexander Graf authored
    The SRR0 and SRR1 registers contain cached values of the PC and MSR
    respectively. They get written to by the hypervisor when an interrupt
    occurs or directly by the kernel. They are also used to tell the rfi(d)
    instruction where to jump to.
    
    Because it only gets touched on defined events that, it's very simple to
    share with the guest. Hypervisor and guest both have full r/w access.
    
    This patch converts all users of the current field to the shared page.
