The hcall H_GET_CPU_CHARACTERISTICS is used by the guest to determine information about the required behaviours and available characteristics of the cpu. Bits may be added to this hcall, the information for which is queried from the hypervisor using the KVM_PPC_GET_CPU_CHAR ioctl. In order to handle the case where additional bits may be added to this hcall, and thus to the ioctl, relax the parsing in qemu so that there is minimal modification of the data before it is passed to the guest.
