I've been running with these patches and a FreeBSD guest for a while now and they work very well, providing big performance improvements in tight memory situations. Thanks! I did have to patch QEMU to enable the hypercalls, however -- it might be worth adding them to the default set since

[PATCH 3/3] KVM: PPC: Book3S HV: Implement H_CLEAR_REF and H_CLEAR_MOD

This adds implementations for the H_CLEAR_REF (test and clear reference bit) and H_CLEAR_MOD (test and clear changed bit) hypercalls. When clearing the reference or change bit in the guest view of the HPTE, we also have to clear it in the real HPTE so that we can detect future references or
