Introduce a new spapr_cap SPAPR_CAP_CCF_ASSIST to be used to indicate the requirement for a hw-assisted version of the count cache flush workaround. The count cache flush workaround is a software workaround which can be used to flush the count cache on context switch. Some revisions of hardware may have a hardware accelerated flush, in which case the software flush can be shortened. This cap is used to set the availability of such hardware acceleration for the count cache flush routine. The availability of such hardware acceleration is indicated by the H_CPU_CHAR_BCCTR_FLUSH_ASSIST flag being set in the characteristics returned from the KVM_PPC_GET_CPU_CHAR ioctl.
