Paul Mackerras bad3b5075e KVM: PPC: Book3s HV: Maintain separate guest and host views of R and C bits ... This allows both the guest and the host to use the referenced (R) and changed (C) bits in the guest hashed page table. The guest has a view of R and C that is maintained in the guest_rpte field of the revmap entry for the HPTE, and the host has a view that is maintained in the rmap entry for the associated gfn. Both view are updated from the guest HPT. If a bit (R or C) is zero in either view, it will be initially set to zero in the HPTE (or HPTEs), until set to 1 by hardware. When an HPTE is removed for any reason, the R and C bits from the HPTE are ORed into both views. We have to be careful to read the R and C bits from the HPTE after invalidating it, but before unlocking it, in case of any late updates by the hardware.
